Implement the man(7) .MR macro, a 2023 GNU extension.
The syntax and semantics is almost identical to mdoc(7) .Xr.

This will be needed for reading the groff manual pages once our port
will be updated to 1.23, and the Linux Manual Pages Project is also
determined to start using it sooner or later.  I did not advocate for
this new macro, but since we want to remain able to read all manual
pages found in the wild, there is little choice but to support it.
At least it is easy to do, they basically copied .Xr.

Support some escape sequences, in particular character escape sequences,
inside \w arguments, and skip most other escape sequences when measuring
the output length in this way because most escape sequences contribute
little or nothing to text width: for example, consider font escapes in
terminal output.

This implementation is very rudimentary.  In particular, it assumes that
every character has the same width.  No attempt is made to detect
double-width or zero-width Unicode characters or to take dependencies on
output devices or fonts into account.  These limitations are hard to
avoid because mandoc has to interpolate \w at the parsing stage when the
output device is not yet known.  I really do not want the content of the
syntax tree to depend on the output device.

Feature requested by Paul <Eggert at cs dot ucla dot edu>, who also
submitted a patch, but i chose to commit this very different patch
with almost the same functionality.
His input was still very valuable because complete support for \w is
out of the question, and consequently, the main task is identifying
subsets of the feature that are needed for real-world manual pages
and can be supported without uprooting the whole forest.

While doing delayed expansion of escape sequences in macro arguments,
correctly check for failure of the in-place expansion function.
If an argument not only does recursive delayed expansion
but infinitely recursive delayed expansion, this bug could
result in an ESCAPE_EXPAND assertion failure.

Thanks to Eric van Gyzen <vangyzen at FreeBSD> for finding this bug
by inspecting FreeBSD source code.

Diff to previous 1.396 (colored) to selected 1.108 (colored)

When parsing a macro argument results in delayed escape sequence
expansion, re-check for all contained escape sequences whether they
need delayed expansion, not just for the particular escape sequences
that triggered delayed expansion in the first place.  This is needed
because delayed expansion can result in strings containing nested
escape sequences recursively needing delayed expansion, too.

This fixes an assertion failure in krb5_openlog(3), see:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=266882

Thanks to Wolfram Schneider <wosch at FreeBSD> for reporting the bug

During identifier parsing, handle undefined escape sequences
in the same way as groff:
* \\ is always reduced to \
* \. is always reduced to .
* other undefined escape sequences are usually reduced to the escape name,
for example \G to G, except during the expansion of expanding escape
sequences having the standard argument form (in particular \* and \n),
in which case the backslash is preserved literally.

Yes, this is confusing indeed.
For example, the following have the same meaning:
* .ds \.   and   .ds .     which is not the same as   .ds \\.
* \*[\.]   and   \*[.]     which is not the same as   \*[\\.]
* .ds \G   and   .ds G     which is not the same as   .ds \\G
* \*[\G]   and   \*[\\G]   which is not the same as   \*[G]   <- sic!

To feel less dirty, have a leaning toothpick, if you are so inclined.

This patch also slightly improves the string shown by the "escaped
character not allowed in a name" error message.

Avoid the layering violation of re-parsing for \E in roff_expand().
To that end, add another argument to roff_escape()
returning the index of the escape name.
This also makes the code in roff_escape() a bit more uniform
in so far as it no longer needs the "char esc_name" local variable
but now does everything with indices into buf[].

Rudimentary implementation of the \A escape sequence, following groff
semantics (test identifier for syntactical validity), not at all
following the completely unrelated Heirloom semantics (define
hyperlink target position).

The main motivation for providing this implementation is to get \A
into the parsing class ESCAPE_EXPAND that corresponds to groff parsing
behaviour, which is quite similar to the \B escape sequence (test
numerical expression for syntactical validity).  This is likely
to improve parsing of nested escape sequences in the future.

Validation isn't perfect yet.  In particular, this implementation
rejects \A arguments containing some escape sequences that groff
allows to slip through.  But that is unlikely to cause trouble even
in documents using \A for non-trivial purposes.  Rejecting the nested
escapes in question might even improve robustnest because the rejected
names are unlikely to really be usable for practical purposes - no
matter that groff dubiously considers them syntactically valid.

Trivial patch to put the roff(7) \g (interpolate format of register)
escape sequence into the correct parsing class, ESCAPE_EXPAND.
Expansion of \g is supposed to work exactly like the expansion
of the related escape sequence \n (interpolate register value),
but since we ignore the .af (assign output format) request,
we just interpolate an empty string to replace the \g sequence.

Surprising as it may seem, this actually makes a formatting difference
for deviate input like ".O\gNx" which used to raise bogus "escaped
character not allowed in a name" and "skipping unknown macro" errors
and printed nothing, whereas now it correctly prints "OpenBSD".

Dummy implementation of the roff(7) \V (interpolate environment variable)
escape sequence.  This is needed to get \V into the correct parsing
class, ESCAPE_EXPAND.

It is intentional that mandoc(1) output is *not* influenced by environment
variables, so interpolate the name of the variable with some decorating
punctuation rather than interpolating its value.

Make roff_expand() parse left-to-right rather than right-to-left.
Some escape sequences have side effects on global state, implying
that the order of evaluation matters.  For example, this fixes the
long-standing bug that "\n+x\n+x\n+x" after ".nr x 0 1" used to
print "321"; now it correctly prints "123".

Right-to-left parsing was convenient because it implicitly handled
nested escape sequences.  With correct left-to-right parsing, nesting
now requires an explicit implementation, here solved as follows:
1. Handle nested expanding escape sequences iteratively.
When finding one, expand it, then retry parsing the enclosing escape
sequence from the beginning, which will ultimately succeed as soon
as it no longer contains any nested expanding escape sequences.
2. Handle nested non-expanding escape sequences recursively.
When finding one, the escape sequence parser calls itself to find
the end of the inner sequence, then continues parsing the outer
sequence after that point.

This requires the mandoc_escape() function to operate in two different
modes.  The roff(7) parser uses it in a mode where it generates
diagnostics and may return an expansion request instead of a parse
result.  All other callers, in particular the formatters, use it
in a simpler mode that never generates diagnostics and always returns
a definite parsing result, but that requires all expanding escape
sequences to already have been expanded earlier.  The bulk of the
code is the same for both modes.
Since this required a major rewrite of the function anyway, move
it into its own new file roff_escape.c and out of the file mandoc.c,
which was misnamed in the first place and lacks a clear focus.

As a side benefit, this also fixes a number of assertion failures
that tb@ found with afl(1), for example "\n\\\\*0", "\v\-\\*0",
and "\w\-\\\\\$0*0".

As another side benefit, it also resolves some code duplication
between mandoc_escape() and roff_expand() and centralizes all
handling of escape sequences (except for expansion) in roff_escape.c,
hopefully easing maintenance and feature improvements in the future.

While here, also move end-of-input handling out of the complicated
function roff_expand() and into the simpler function roff_parse_comment(),
making the logic easier to understand.

Since this is a major reorganization of a central component of
mandoc(1), stability of the program might slightly suffer for a few
weeks, but i believe that's not a problem at this point of the
release cycle.  The new code already satisfies the regression suite,
but more tweaking and regression testing to further improve the
handling of various escape sequences will likely follow in the near
future.

Split a new function roff_parse_comment() out of roff_expand() because this
functionality is not needed when called from roff_getarg().  This makes the

or macro, including context-dependent error handling inside tbl(7) code

This fixes an assertion failure triggered by ".if 1 .ce" inside tbl(7)
code, found by tb@ using afl(1).

As a side benefit for readability, only one place remains in the
code that calls the main handler functions for the various roff(7)
requests.  This patch also improves column numbers in some error

Surprisingly, groff supports multiple copy mode escapes at the
beginning of an escape sequence: \, \E, \EE, \EEE, and so on all do
the same outside copy mode, so let them do the same in mandoc(1), too.

This fixes an assertion failure triggered by \EE*X that tb@ found
with afl(1).  The first E was consumed by roff_expand(), but that
function failed to recognize the escape sequence as the expansion
of a user-defined string and handed it over to mandoc_escape(),
which consumed the second E and then died on an assertion because
it is not prepared to handle user-defined strings.  Fix this by
letting *both* functions handle arbitrary numbers of 'E's correctly.

Do not leak 64 bytes of heap memory every time a manual page calls
a user-defined macro.  Calls of standard mdoc(7) and man(7) macros
were unaffected, so the effect on OpenBSD manual pages was small,
about 80 Kilobytes grand total for a full run of "makewhatis
/usr/share/man".

Argument expansion contexts for user-defined macros are stored on
a stack that grows as needed if calls of user-defined macros are
nested or recursive.  Individual stack entries contain dynamically
allocated arrays of pointers to arguments; these argument arrays
also grow as needed if user-defined macros take more than eight
arguments.  The mistake was that argument arrays of already
initialized expansion contexts were leaked rather than reused on
subsequent macro calls.

I found this issue in a systematic hunt for memory leaks after
Michael <Stapelberg at Debian> reported memory exhaustion problems
on the production server manpages.debian.org.  This sub-Megabyte
leak is not the cause of Michael's trouble, though, where Gigabytes
of memory are being wasted.  We are still investigating whether the
original problem may be related to his supervisor process, which is
written in Go, rather than to mandoc.

Support two-character font names (BI, CW, CR, CB, CI)

Get rid of the TBL_CELL_BOLD and TBL_CELL_ITALIC flags and use
the usual ESCAPE_FONT* enum mandoc_esc members from mandoc.h instead,
which simplifies and unifies some code.

While here, also support CB and CI in roff(7) \f escape sequences
and in roff(7) .ft requests for all output modes.  Using those is
certainly not recommended because portability is limited even with
groff, but supporting them makes some existing third-party manual
pages look better, in particular in HTML output mode.

Bug-compatible with groff as far as i'm aware, except that i consider
font names starting with the '\n' (ASCII 0x0a line feed) character
so insane that i decided to not support them.

Fully support explicit tagging of .Sh and .Ss.
This fixes the offset of two lines in terminal output
and this improves HTML output by putting the id= attribute
and <a> element into the respective <h1> or <h2> element rather
than writing an additional <mark> element.

To that end, introduce node flags NODE_ID (to make the node a link
target, for example by writing an HTML id= attribute or by calling
tag_put()) and NODE_HREF (to make the node a link source, used only
in HTML output, used only to write an <a class="permalink"> element).

In particular:
* In the validator, generalize the concept of the "next node"
such that it also works before .Sh and .Ss.
* If the first argument of .Tg is empty, don't forget to complain
if there are additional arguments, which will be ignored.
* In the terminal formatter, support writing of explicit tags
for all kinds of nodes, not just for .Tg.
* In deroff(), allow nodes to have an explicit string representation
even when they aren't text nodes.  Use this for explicitly tagged
section headers.  Suprisingly, this is sufficient to make HTML
output work, without explicit code changes in the HTML formatter.
* In syntax tree output, display NODE_ID and NODE_HREF.

Do not fail an assertion when a high level macro occurs in the body

In the past, generating comment nodes stopped at the .TH or .Dd
macro, which is usually close to the beginning of the file, right
after the Copyright header comments.  But espie@ found horrible
input files in the textproc/fstrcmp port that generate lots of parse
nodes before even getting to the header macro.  In some formatters,
comment nodes after some kinds of real content triggered assertions.

So make sure generation of comment nodes stops once real content is
encountered.

Let roff_getname() end the roff identifier at a tab character
and audit all its callers whether termination is handled correctly.

Resulting improvements:
* An escape or tab ending the macro name in a macro invocation
is discarded, and argument processing is started after it.
* An escape or tab ending a name in ".if d" and ".if r" is preserved.
* An escape ending a name in ".ds" causes the whole request to be ignored.
* A tab ending a name in ".ds" becomes part of the string.
* An escape or tab ending a name in ".rm"
causes the rest of the line to be ignored.
* An escape or tab ending the first name in ".als", ".rn", or ".nr"
causes the whole request to be ignored.

Some high-level block macros have an effect similar to temporarily
suspending no-fill mode during their head.  Model this with an
additional roff parser state flag ROFF_NONOFILL.  That is much
simpler than it would be to save and restore the ROFF_NOFILL flag
itself, in particular since the latter can be switched (with lasting
effect) by the .nf and .fi requests even while its effect is
temporarily suspended.

This commit does not change formatting yet, but prepares for future
formatting simplifications and improvements.

Cleanup, no functional change:

The struct roff_man used to be a bad mixture of internal parser
state and public parsing results.  Move the public results to the
parsing result struct roff_meta, which is already public.  Move the
rest of struct roff_man to the parser-internal header roff_int.h.

Since the validators need access to the parser state, call them
from the top level parser during mparse_result() rather than from
the main programs, also reducing code duplication.

This keeps parser internal state out of thee main programs (five
in mandoc portable) and out of eight formatters.

Rename mandoc_getarg() to roff_getarg() and pass it the roff parser
struct as an argument such that after copy-in, it can call roff_expand()
once again, which used to be called roff_res() before this.  This
fixes a subtle low-level roff(7) parsing bug reported by Fabio
Scotoni <fabio at esse dot ch> in the 4.4BSD-Lite2 mdoc.samples(7)
manual page, because that page used an escaped escape sequence in
a macro argument.

To expand escaped escape sequences in quoted mdoc(7) arguments, too,
stop bypassing the call to roff_getarg() in mdoc_argv.c, function args()
for this case.  This does not solve the case of escaped escape sequences
in quoted .Bl -column phrases yet.

Because roff_expand() can make the string longer, roff_getarg() can no
longer operate in-place but needs to malloc(3) the returned string.
In the high-level parsers, free(3) that string after processing it.

move the function mandoc_getarg() from mandoc.c to roff.c.  It was
misplaced in mandoc.c in the first place; that file is intended for

Several improvements to escape sequence handling.

* Add the missing special character \_ (underscore).
* Partial implementations of \a (leader character)
and \E (uninterpreted escape character).
* Parse and ignore \r (reverse line feed).
* Add a WARNING message about undefined escape sequences.
* Add an UNSUPP message about unsupported escape sequences.
* Mark \! and \? (transparent throughput)
and \O (suppress output) as unsupported.
* Treat the various variants of zero-width spaces as one-byte escape
sequences rather than as special characters, to avoid defining bogus
forms with square brackets.
* For special characters with one-byte names, do not define bogus
forms with square brackets, except for \[-], which is valid.
* In the form with square brackets, undefined special characters do not
fall back to printing the name verbatim, not even for one-byte names.
* Starting a special character name with a blank is an error.
* Undefined escape sequences never abort formatting of the input
string, not even in HTML output mode.
* Document the newly handled escapes, and a few that were missing.
* Regression tests for most of the above.

Move the node relinking function to the roff library where it belongs.

In validation functions, only look at the node itself, at previous

such that only nodes are inspected which are already validated.

Quirk reported by millert@.

While here, tweak the rest of the function body of roff_cond_text()

Also correctly interpolate arguments during nested macro execution

* All definitions can be used for .if d tests and .am appending.

* Predefined for \* expansion.
* Standard macros, original or renamed, for macro calling.

Several related improvements while here:
* Do not return string table entries that have explicitly been removed.
* Do not create a rentab entry when trying to rename a non-existent macro.
* Clear an existing rentab entry when the external interface
roff_setstr() is called with its name.
* Avoid trailing blanks in macro lines generated from renamed
and from aliased macros.
* Delete the duplicate __m*_reserved[] tables, just use roff_name[].

Implement the roff(7) .rn (rename macro or string) request.
Renaming a user-defined macro is very simple: just copy
the definition to the new name and delete the old name.
Renaming high-level macros is a bit tricky: use a dedicated
key-value-table, with non-standard names as keys and standard
names as values.  When a macro is found that is not user-defined,
look it up in the "renamed" table and translate it back to the
standard name before passing it on to the high-level parsers.

Pure preprocessor implementation of the roff(7) .ec and .eo requests
(escape character control), touching nothing after the preprocessing
stage and keeping even the state variable local to the preprocessor.
Since the escape character is also used for line continuation, this
requires pulling the implementation of line continuation from the
input reader to the preprocessor, which also considerably shortens
the code required for that.

When the escape character is changed, simply let the preprocessor
replace bare by escaped backslashes and instances of the non-standard
escape character with bare backslashes - that's all we need.

Oh, and if anybody dares to use these requests in OpenBSD manuals,
sending a medium-sized pack of axe-murderers after them might be a
worthwhile part of the punishment, but probably insuffient on its own.

available to both the parser loop and the validation pass.

Major character table cleanup:
* Use ohash(3) rather than a hand-rolled hash table.
* Make the character table static in the chars.c module:
There is no need to pass a pointer around, we most certainly
never want to use two different character tables concurrently.
* No need to keep the characters in a separate file chars.in;
that merely encourages downstream porters to mess with them.
* Sort the characters to agree with the mandoc_chars(7) manual page.
* Specify Unicode codepoints in hex, not decimal (that's the detail
that originally triggered this patch).

Setting the "last" member of struct roff_node was done at an extremely
weird place.  Move it to the obviously correct place.
Surprisingly, this didn't cause any misformatting in the test suite
or in any base system manuals, but i cannot believe the code was
really correct for all conceivable input, and it would be very hard
to verify.  At the very least, it cannot have worked for man(7).

Cope with another one of the many kinds of DocBook stupidity:

Instead of just using .br, DocBook sometimes fiddles with the
utterly unportable internal register \n[an-break-flag] that is
only available in the GNU implementation of man(7) and then arms
an input line trap to call the equally unportable internal macro
.an-trap that, in the GNU implementation, inspects that variable;
all the world is GNU, isn't it?

Since naddy@ reports that quite a few ports manuals suffer from
this insanity, let's just translate it to the intended .br.

Split the -Werror message level into -Werror (broken manual, probably
using mandoc is better than using groff) and -Wunsupp (manual using
unsupported low-level roff(7) feature, probably using groff is better
than using mandoc).  Once this feature is complete, it is intended
to help porting, making the decision whether to USE_GROFF easier.

As a first step, distinguish four classes of roff(7) requests:
1. Supported (currently 24 requests)
2. Currently ignored because unimportant (120)  ->  no message
3. Ignored for good because insecure (14)  ->  -Werror
4. Currently unsupported (68)  ->  these trigger the new -Wunsupp messages

Move main format autodetection from the parser dispatcher to the
roff parser where .Dd and .TH are already detected, anyway.  This
improves robustness because it correctly handles whitespace or an
alternate control character before Dd.  In the parser dispatcher,
provide a fallback looking ahead in the input buffer instead of
always assuming man(7).  This corrects autodetection when Dd is

The previous commit to this file broke the control flow keywords \{ and \}
when they immediately follow a request or macro name, without intervening
whitespace.  Minimal fix.

The lesson learnt here is that, despite their appearance, \{ and \} are
not escape sequences, so never skip them when parsing for names.

Three bugfixes related to the closing of conditional blocks:
1. Handle more than one `\}' on macro lines, as it was already done
for text lines.
2. Do not treat `\}' as a macro invocation after a dot at the beginning
of a line.  That allows more than one `\}' to work on lines starting
with `.\}'.  It also simplifies the code.
3. Do not complain about characters following `\}'.  Those are not lost,
but handled normally both on text and macro lines.

Another 25% speedup for mandocdb(8) -Q mode, found with gprof(1).
For /usr/share/man, we only need 56% of the time of makewhatis(8) now.

In groff, user-defined macros clashing with mdoc(7) or man(7)
standard macros are cleared when parsing the .Dd or .TH macro,
respectively.  Of course, we continue doing that in standard mode
to assure full groff bug compatibility.

However, in -Q mode, full groff bug compatibility makes no sense
when it's unreasonably expensive, so skip this step in -Q mode.
Real-world manuals hardly ever redefine standard macros,
that's terrible style, and if they do, it's pointless to do so
before .Dd or .TH because it has no effect.  Even if someone does,
it's extremely unlikely to break mandocdb(8) -Q parsing because we
abort the parse sequence after the NAME section, anyway.

So if you manually redefine .Sh, .Nm, .Nd, or .SH in a way that doesn't
work at all and rely on .Dd or .TH to fix it up for you, your broken
manual will no longer get a perfect apropos(1) entry until you re-run
mandocdb(8) without -Q.  It think that consequence is acceptable
in order to get a 25% speedup for everyone else.

Original code from Christos Zoulas, NetBSD rev. 1.11-1.13, April 3, 2013.

I tweaked the code as follows:
* In roff_getnum(), don't skip a minus that isn't followed by a digit.
* In roff_getop(), do not handle "!=", groff doesn't support it either.
* In roff_evalcond(), treat negative numbers as false, like groff.
Besides, make the interfaces of roff_getnum() and roff_getop() more
similar to each other and simplify parts of the code a bit.

Expand references to number registers in exactly the same way as
references to user-defined strings.  While here, make number registers
signed int, like in groff.

Inspired by NetBSD roff.c rev. 1.8 and read.c rev. 1.7
written by Christos Zoulas on March 21, 2013, but implemented
in a completely different way, without hacking into read.c,
where this functionality really doesn't belong.

Support setting arbitrary roff(7) number registers,
preserving read support for the ".nr nS" SYNOPSIS state register.

Inspired by NetBSD roff.c rev. 1.18 (Christos Zoulas, March 21, 2013),
but implemented differently.  I don't want to have yet another different
implementation of a hash table in mandoc - it would be the second one
in roff.c alone and the fifth one in mandoc grand total.
Instead, i designed and implemented roff_setreg() and roff_getreg()
to be similar to roff_setstrn() and roff_getstrn().

Once we feel the need to optimize, we can introduce one common
hash table implementation for everything in mandoc.

Cleanup suggested by gcc-4.8.1, following hints by Christos Zoulas:
- avoid bad qualifier casting in roff.c, roff_parsetext()
  by changing the mandoc_escape arguments to "const char const **"
- avoid bad qualifier casting in mandocdb.c, index_merge()
- do not complain about unused variables in test-*.c
- garbage collect a few unused variables elsewhere

Rudimentary implementation of the .it request (input line trap).
As with any low-level roff request involving subtle interactions
with macro internals, this implementation is not exact, but it
does handle the simplest cases.

This request occurs in man(7) code generated from DocBook,
for example mysql(1) and yasm_arch(7).
Thanks to brad@ for reporting the issue back in January 2011.

In groff, trying to redefine standard man(7) macros before .TH has no effect;
after .TH, it works.  Trying to redefine standard mdoc(7) macros before .Dd
works when calling groff with the -mdoc command line option, but does not
when calling groff with -mandoc; after .Dd, it always works.

Arguably, one might call that buggy behaviour in groff, but it is very
unlikely that anybody will change groff in this respect (certainly, i'm
not volunteering).  So let's be bug-compatible.

This fixes the vertical spacing in sox(1).

Add `cc' support.
This was reported by espie@ and in the TODO.
Caveat: `cc' has buggy behaviour when invoked in groff(1) and followed
by a line-breaking control character macro, e.g., in a -man doc,

  .cc |
  .B foo
  'B foo
  |cc
  'B foo

will cause groff(1) to behave properly for `.B' but inline the macro
definition for `B' when invoked with the line-breaking macro.

Fix another regression introduced in 1.11.7:
If a string is defined in terms of itself, the REPARSE_LIMIT in read.c
used to break the cycle.  This no longer works since all the work
is now done in the function roff_res(), looping indefinitely.

Make this loop finite by arbitrarily limiting the number of times one
string may be expanded; when that limit is reached, leave the remaining
string references unexpanded.

This changes behaviour compared to 1.11.5, where the whole line would
have been dropped.  The new behaviour is better because it loses less
information.  We don't want to imitate groff-1.20.1 behaviour anyway
because groff aborts parsing of the whole file.

First, roff_res() has no need to invoke ROFF_RERUN: since it's executed
before any other roff processing occurs, it's Ok to just let it do its
thing and pass through.  Also, make sure this function is ALWAYS called,
not just when first_string is defined.

Second, add a new function, roff_parsetext(), that post-processes

Most important move in getting predefined strings entirely contained
within roff.c.  These are now grokked from a table in the roff
allocation routine and rest in the newly-created predefs.in (for
consistency with chars.in).  This is a first implementation and will
likely be optimised along with the ds/de lookup table itself.

This allows mandoc-defined predefined strings to be correctly removed or
whatnot; earlier they couldn't.  What will follow is the stripping-away
of all predefined-string crud in the other parts of the system.

Carefully let mandoc_getcontrol() handle libroff's detection of a macro
line.  Note that we now properly ignore \.", which earlier would have
been pushed through macro detection.  This required attention to all
entries of roff_parse().

This removes a TODO by schwarze@ to the effect that \. can be a control
character, which is now handled in mandoc_getcontrol().

Consolidate messages.  Have all parse-time messages (in libmdoc,
libroff, etc., etc.) route into mandoc_msg() and mandoc_vmsg(), for the

into the allocation routines instead of mandocmsg and a void pointer.
Then, move some of the functionality of the old mmsg() into read.c's
mparse_mmsg() (check against wlevel and setting of file_status) and use
main.c's mmsg() as simply a printing tool.

Unify roff macro argument parsing (in roff.c, roff_userdef()) and man macro
argument parsing (in man_argv.c, man_args()), both having different bugs,
to use one common macro argument parser (in mandoc.c, mandoc_getarg()),
because from the point of view of roff, man macros are just roff macros,
hence their arguments are parsed in exactly the same way.

While doing so, fix these bugs:
 * Escaped blanks (i.e. those preceded by an odd number of backslashes)
   were mishandled as argument separators in unquoted arguments to
   user-defined roff macros.
 * Unescaped blanks preceded by an even number of backslashes were not
   recognized as argument separators in unquoted arguments to man macros.
 * Escaped backslashes (i.e. pairs of backslashes) were not reduced
   to single backslashes both in unquoted and quoted arguments both
   to user-defined roff macros and to man macros.
 * Escaped quotes (i.e. pairs of quotes inside quoted arguments) were
   not reduced to single quotes in man macros.

OK kristaps@

Note that mdoc macro argument parsing is yet another beast for no good
reason and is probably afflicted by similar bugs.  But i don't attempt
to fix that right now because it is intricately entangled with lots of
unrelated high-level mdoc(7) functionality, like delimiter handling and
column list phrase handling.  Disentagling that would waste too much
time now.

Initial tbl framework.  Parse point is in libroff, which keeps a
reference to a current tbl parse and routes ALL text into the tbl parse
after stripping reserved words and making block-level pre-processing
(e.g., `ig').  This is consistent with an analysis of embedded `TS/TE'
in manuals with sprinkled -mdoc, roff, and -man macros.

Fact of a parse is exposed to main.c by a return value (ROFF_TBL), which
will trigger main.c to add a foreign parsed body to the -mdoc or -man
parse stream.  This interface isn't in yet, but will follow the
parse-text functions in both libraries.  I put this login in main.c
because I don't want libroff calling directly into libmdoc or libman.

As a consequence, a parsed row can be pushed directly into any -mdoc or
-man context (put a `Bd -literal -offset indent' into a `TE/TS' block to
see why this is necessary).  It will then absorb formatting cues in the
front-ends.

A note on naming.  I decided on libroff.h instead of tbl.h because this
is purely within the roff layer.  Separate tbl implementations will
need, then, to interface with libroff.  This is "how it should be"
because tbl is tightly linked with roff in terms of `ds' and other
formatting macros, as well as, of course, special characters and other
roffisms.

Implement a simple, consistent user interface for error handling.
We now have sufficient practical experience to know what we want,
so this is intended to be final:
- provide -Wlevel (warning, error or fatal) to select what you care about
- provide -Wstop to stop after parsing a file with warnings you care about
- provide consistent exit status codes for those warnings you care about
- fully document what warnings, errors and fatal errors mean
- remove all other cruft from the user interface, less is more:
- remove all -f knobs along with the whole -f option
- remove the old -Werror because calling warnings "fatal" is silly
- always finish parsing each file, unless fatal errors prevent that
This commit also includes a couple of related simplifications behind
the scenes regarding error handling.

Sascha Wildner (DragonFly BSD) agree with the general direction.

Fixed condition of `\}' closing a conditional at the start of the line.

Fixed flushed-out condition of \} causing subsequent arguments to be
truncated, when in fact the whole line should be passed through (if the
conditional succeeds) to the front-end and the \} ignored there.

Added regression test of this behaviour.

Give libroff an extremely simple table-lookup instead of iterating over
each and every macro.  The table keys on the first character then walks
a chain.  Good enough for now.

Support for the general case of `if', which will boil out into other
constructs: single-level and multi-level blocks; nested, varied-level
blocks; recalculating buffer (begin) boundaries pushed correctly into

on, for things like `.ie n .TH FOO 1' then `.el .Dd Mdocdate'.  Read
it and weep.
