Align to the new, sane behaviour of the groff_mdoc(7) .Dd macro:
without an argument, use the empty string, and always concatenate
all arguments, no matter their number.
This allows reducing the number of arguments of mandoc_normdate()
and some other simplifications, at the same time polishing some
error messages by adding the name of the macro in question.

Fix mandoc_normdate() and the way it is used.
In the past, it could return NULL but the calling code wasn't prepared
to handle that.  Make sure it always returns an allocated string.
While here, simplify the code by handling the "quick" attribute
inside mandoc_normdate() rather than at multiple callsites.

Triggered by deraadt@ pointing out
that snprintf(3) error handling was incomplete in time2a().

Do not print the style message "missing date" when the date is given
as "$Mdocdate$" without an actual date.  That is the canonical way to
write a new manual page and not bad style at all.
Misleading message reported by kn@ on tech@.

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.

As a first step towards making roff_res() callable from mandoc_getarg(),
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
utilities needed both by parsers and by formatters, while reading
macro arguments in copy mode is purely a task of the roff(7) parser.
Needed as a preliminary for an upcoming bugfix.
No code change.

Yet another round of improvements to manual font selection.

Unify handling of \f and .ft.
Support \f4 (bold+italic).
Support ".ft BI" and ".ft CW" for terminal output.
Support the .ft request in HTML output.
Reject the bogus fonts \f(C1, \f(C2, \f(C3, and \f(CP.
In regress.pl, only strip leading whitespace in math mode.

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.

Cleanup, no functional change:
Now that message handling is properly encapsulated,
remove struct mparse pointers from four structs (roff, roff_man,
tbl_node, eqn_node) and from the argument lists of five functions
(roff_alloc, roff_man_alloc, mandoc_getarg, tbl_alloc, eqn_alloc).
Except for being passed to the main program as an opaque object,
it now only occurs in read.c, as it should, and not across 15 files
like in the past.

Almost mechanical diff to remove the "struct mparse *" argument
from mandoc_msg(), where it is no longer used.
While here, rename mandoc_vmsg() to mandoc_msg() and retire the
old version:  There is really no point in having another function
merely to save "%s" in a few places.

Implement the \f(CW and \f(CR (constant width font) escape sequences
for HTML output.  Somewhat relevant because pod2man(1) relies on this.
Missing feature reported by Pali dot Rohar at gmail dot com.

Note that constant width font was already correctly selected before
this when required by semantic markup.  Only attempting physical
markup with the low-level escape sequence was ineffective.

Issue a STYLE message when normalizing the date format in .Dd/.TH.
Leah Neukirchen pointed out that mdoclint(1) used to warn about a
leading zero before the day number, so we know that both NetBSD and
Void Linux want the message.  It does no harm on OpenBSD because
Mdocdate always does the right thing anyway.
jmc@ agrees that it makes sense in contexts not using Mdocdate.

Partial implementation of \h (horizontal line drawing function).
A full implementation would require access to output device properties
and state variables (both only available after the main parser has
finalized the parse tree) before numerical expansions in the roff
preprocessor (i.e., before the main parser is even started).

Not trying to pull that stunt right now because the static-width
implementation committed here is sufficient for tcl-style manual pages
and already more complicated than i would have suspected.

I have no idea how it happened that \B, \H, \h, \L, and \l got
mapped to ESCAPE_NUMBERED (which is for \N and only for \N), that
made no sense at all.  Properly remap them to ESCAPE_IGNORE.

While here, move \B and \w from the group taking number arguments
to the group taking string arguments; right now, that doesn't imply
any functional change, but if we ever go ahead and implement a
parser for roff(7) numerical expressions, it will suddenly start
to matter, and cause confusion.

Support the alternative syntax \C'uXXXX' for Unicode characters.

Bug reported by Bjarni Ingi Gislason <bjarniig at rhi dot hi dot is>

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

Implement the roff(7) font-escape sequence \f(BI "bold+italic".
This improves the formatting of about 40 base manuals
and reduces groff-mandoc formatting differences in base by about 5%.

Improve handling of the roff(7) "\t" escape sequence:
* Parsing macro arguments has to be done in copy mode,
  which implies replacing "\t" by a literal tab character.
* Otherwise, render "\t" as the empty string, not as a 't' character.

This fixes formatting of the distfile example in the oldrdist(1) manual.
This also shows up in the unzip(1) manual as one of several issues
preventing the removal of USE_GROFF from the archivers/unzip port.
Thanks to espie@ for attracting my attention to the unzip(1) manual.

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.

While i already got my fingers dirty on mandoc_escape(),
profit of the occasion to pull out some spaghetti, that is,
three confusing variables and fourteen pointless assignments
among them; instead, always operate on the official pointers
**start, **end, and *sz, each of which conveys an obvious meaning.

No functional change intended, and the new tests confirm that
everything still (err...) "works", as far as that word can be
applied to the kind of roff(7) mock-up code i'm polishing here.

Make recursive parsing of roff(7) escapes actually work in the general case,
in particular when the inner escapes are preceded or followed by other terms.
While doing so, remove lots of bogus code that was trying to make pointless
distinctions between numeric and non-numeric escape sequences, while both
actually share the same syntax and we ignore the semantics anyway.

This prevents some of the strings defined in the pod2man(1) preamble
from producing garbage output, in particular in scandinavian words.
Of course, proper rendering of scandinavian national characters
cannot be expected even with these fixes.

Implement the roff \z escape sequence, intended to output the next
character without advancing the cursor position; implement it to
simply skip the next character, as it will usually be overwritten.

With this change, the pod2man(1) preamble user-defined string \*:,
intended to render as a diaeresis or umlaut diacritic above the
preceding character, is rendered in a slightly less ugly way,
though still not correctly.  It was rendered as "z.." and is now
rendered as ".".

Given that the definition of \*: uses elaborate manual \h positioning,
there is little chance for mandoc(1) to ever render it correctly,
but at least we can refrain from printing out a spurious "z", and
we can make the \z do something semi-reasonable for easier cases.

Handle \N numbered character escapes the same way as groff:
If \N is followed by a digit, ignore \N and the digit.
If \N is followed by a non-digit, the next non-digit
ends the character number; the two delimiters need not match.
Kristaps calls that "gross, but not our fault".

For now, i'm fixing \N only.  Other escapes taking numeric arguments
may or may not need similar handling, but \N is by far the most
important for practical purposes.

 (2) add compat_getsubopt.c (from OpenBSD) and test-getsubopt.c
 (3) add test-strptime.c for HAVE_STRPTIME
 (4) add ifdef bits here and there, where necessary
 (5) remove some harmless unportable stuff (u_char, localtime_r)

Remove a2roffdeco() and mandoc_special() functions and replace them with
a public (mandoc.h) function mandoc_escape(), which merges the
functionality of both prior functions.

Reason: code duplication.  The a2roffdeco() and mandoc_special()
functions were pretty much the same thing and both quite complex.  This
allows one function to receive improvements in (e.g.) subexpression
handling and performance, instead of having to replicate functionality.

As such, the mandoc_escape() function already handles a superset of the
escapes handled in previous versions and has improvements in performance
(using strcspn(), for example) and reliable handling of subexpressions.

This code Works For Me, but may need work to catch any regressions.
Since the benefits are great (leaner code, simpler API), I'd rather have
it in-tree than floating as a patch.

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.

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.

Text ending in a full stop, exclamation mark or question mark
should not flag the end of a sentence if:

1) The punctuation is followed by closing delimiters
and not preceded by alphanumeric characters, like in
"There is no full stop (.) in this sentence"

or

2) The punctuation is a child of a macro
and not preceded by alphanumeric characters, like in
"There is no full stop
.Pq \&.
in this sentence"

"looks fine" to kristaps@; tested by jmc@ and sobrado@

Clean up mandoc_special() (in order later to catch \m).  It also flags
several syntactic errors that weren't caught before.

Also un-puke chars.c on zero-length \[].

FILE REMOVED

Renamed mandoc.c to libmandoc.c.  This is in the efforts of getting a
cleaner namespace for functions across the entire system (mandoc.h:
getting parsed-string values, or declarations necessary for the AST
data), and compiler functions (libmandoc.h: back-end functions and
declarations).

Squash bug noted by Ulrich Spoerlein where "-" were being converted to
ASCII_HYPH, as per normal, but were screwing up mandoc_special().  Fixed
by making mandoc_special() first check isspace() instead of ! isgraph(),
then normalise its string as it passes out.  This require de-constifying
some validation routines not already de-constified (those in libman),
but that's ok, because I'd like to be pushing actions into validation
routines to save on space and redundant calculations.

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.

Modified version of Ingo Schwarze's patch for hyphen-breaking.
Breakable hyphens are cued in the back-ends (with ASCII_HYPH) and acted
upon in term.c or ignored in html.c.

Also cleaned up XML decl printing (no need for extra vars).
