Introduce the concept of nodes that are semantically transparent:
they are skipped when looking for previous or following high-level
macros.  Examples include roff(7) .ft, .ll, and .ta, mdoc(7) .Sm
and .Tg, and man(7) .DT and .PD.  Use this concept for a variety
of improved decisions in various validators and formatters.

While here,
* remove a few const qualifiers on struct arguments that caused trouble;
* get rid of some more Yoda notation in the vicinity;
* and apply some other stylistic improvements in the vicinity.

I found this class of issues while considering .Tg patches from kn@.

Introduce a new mdoc(7) macro .Tg ("tag") to explicitly mark a place
as defining a term.  Please only use it when automatic tagging does
not work.  Manual page authors will not be required to add the new
macro; using it remains optional.  HTML output is still rudimentary
in this version and will be polished later.

Thanks to kn@ for reminding me that i have been considering since
BSDCan 2014 whether something like this might be useful.  Given
that possibilities of making automatic tagging better are running
out and there are still several situations where automatic tagging
cannot do the job, i think the time is now ripe.

Feedback and no objection from millert@; OK espie@ inoguchi@ kn@.

Oops, i forgot to adjust this file to the changes in roff.h rev. 1.67.
Provide a handler for the new .nf and .fi roff(7) request nodes,
avoiding a potential crash, and correctly restore the former fill
more at .Ed even when there was .nf or .fi inside the block.

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.

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.

In the validators, translate obsolete macro aliases (Lp, Ot, LP, P)
to the standard forms (Pp, Ft, PP) up front, such that later code
does not need to look for the obsolete versions.
This reduces the risk of incomplete handling.

The upcoming .while request will have to re-execute roff(7) lines
parsed earlier, so they will have to be saved for reuse - but the
read.c preparser does not know yet whether a line contains a .while
request before passing it to the roff parser.  To cope with that,
save all parsed lines for now.  Even shortens the code by 20 lines.

Remove the implicit display feature of .Lk because it was inconsistent
across output devices, counter-intuitive, and resulted in ugly

Naive implementation of the roff(7) .po (page offset) request.

This clearly works when .po is called on the top level, but might
not be sophisticated enough if people call .po inside indentation-changing
contexts, but i haven't seen that in manual pages (yet :).

The .Nm macro does not only use the default name when it has no

Arcane issue found in the FreeBSD cxgbetool(8) manual that Baptiste
Daroussin <bapt at FreeBSD> sent me long ago for a different reason.

While solving this, switch to the new technique of doing text
production in the validator, reducing code duplication in the
formatters, which also makes -Ttree output clearer.

Delete the mdoc_node.pending pointer and the function calculating
it, make_pending(), which was the most difficult function of the
whole mdoc(7) parser.  After almost five years of maintaining this
hellhole, i just noticed the pointer isn't needed after all.

Blocks are always rewound in the reverse order they were opened;
that even holds for broken blocks.  Consequently, it is sufficient
to just mark broken blogs with the flag MDOC_BROKEN and breaking
blocks with the flag MDOC_ENDED.  When rewinding, instead of iterating
the pending pointers, just iterate from each broken block to its
parents, rewinding all that are MDOC_ENDED and stopping after
processing the first ancestor that it not MDOC_BROKEN.  For ENDBODY
markers, use the mdoc_node.body pointer in place of the former
mdoc_node.pending.

This also fixes an assertion failure found by jsg@ with afl,
test case #467 (Bo Bl It Bd Bc It), where (surprise surprise)
the pending pointer got corrupted.

Improved functionality, minus one function, minus one struct field,
minus 50 lines of code.

consistent with how mdoc behaves (and produces more readable manuals).

basic implementation of -Tman .Bl -tag

multiple fixes to -Tascii .HP rendering:
* do not add an excessive blank line before the block
* in literal mode, start a new line after the tag

getting this to work requires some general (print_man_node) fixes:
* in literal mode, break the output line at the end of each
input line, not just after those input lines ending in text
* but don't break it when there was no output on the line
* and adjust the margins after the .HP tag

these general fixes require an adjustment to -Tascii .TP rendering:
* set up NOBREAK mode before the body, not after the head

finally, based on all this, implement -Tman .Bl -hang in terms of .HP

OpenBSD rev. 1.84 and 1.29, respectively

Tidy up -Tman output.  This has NO functional change: (1) introduced a
state struct instead of using global statics; (2) documented throughout
the file; (3) fixed a situation of reaching past the end of our buffer
for zero-length strings; (4) alpha-ordered the functions.  (1) and (3)
ok schwarze@.  (2) and (4) are purely style and documentation.

If -Tman is specified and input is -man, echo the preprocessed (`so'
replaced by file) input.  This replaces earlier behaviour of doing
nothing, which I found unexpected (mandoc should always output).

This requires a buffer in read.c that saves the input lines before being
parsed, with a special hook if `so' is invoked.  This buffer is just
flushed to output if -mman is the input.

While mucking around doing this, I also alpha-ordered the mandoc.h
functions.

Ok schwarze@, with no screaming when the polished patch was published.
