in tag.{h,c} and {mdoc,man}_validate.c
and into a formatting part including command line argument checking
in term_tag.{h,c}, html.c, and {mdoc|man}_{term|html}.c.
Immediate functional benefits include:
* Improved prioritization of automatic tags for .Em and .Sy.
* Avoiding bogus automatic tags when .Em, .Fn, or .Sy are explicitly tagged.
* Explicit tagging of .Er and .Fl now works in HTML output.
* Automatic tagging of .IP and .TP now works in HTML output.
But mainly, this patch provides clean earth to build further improvements on.
Technical changes:
* Main program: Write a tag file for ASCII and UTF-8 output only.
* All formatters: There is no more need to delay writing the tags.
* mdoc(7)+man(7) formatters: No more need for elaborate syntax tree inspection.
* HTML formatter: If available, use the "string" attribute as the tag.
* HTML formatter: New function to write permalinks, to reduce code duplication.
Style cleanup in the vicinity while here:
* mdoc(7) terminal formatter: To set up bold font for children,
defer to termp_bold_pre() rather than calling term_fontpush() manually.
* mdoc(7) terminal formatter: Garbage collect some duplicate functions.
* mdoc(7) HTML formatter: Unify <code> handling, delete redundant functions.
* Where possible, use switch statements rather than if cascades.
* Get rid of some more Yoda notation.
The necessity for such changes was first discussed with kn@, but i didn't
bother him with a request to review the resulting -673/+782 line patch.

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@.

1. Relax checking to accept function types of the form
"ret_type (fname)(args)" (suggested by Yuri Pankov <yuripv dot net>).
2. Tighten checking to require the closing parenthesis.

causes horrible churn anyway, profit of the opportunity to stop
excessive testing, such that this is hopefully the last instance
of such churn. Consistently use OpenBSD RCS tags, blank .Os,
blank fourth .TH argument, and Mdocdate like everywhere else.
Use -Ios=OpenBSD for platform-independent predictable output.

and of called macros.
This bug affects almost all macros, and fixing it simplifies the
code. It is amazing that the bogus ARGS_QWORD feature got implemented
in the first place, and then carrier along for more than eight years
without anybody ever noticing that it was pointless.

input files in -T markdown output mode by default and only mark
those files with SKIP_MARKDOWN that are not to be tested.
Much easier to read, and almost minus 40 lines of Makefile code.

inconsistent behaviour. In short:
Some macros are displayed differently in the SYNOPSIS
section, particularly Nm, Cd, Fd, Fn, Fo, In, Vt, and Ft.
All of these macros are output on their own line. If two
such dissimilar macros are pair-wise invoked (except for Ft
before Fo or Fn), they are separated by a vertical space,
unless in the case of Fo, Fn, and Ft, which are always
separated by vertical space.
Behaviour ok Jason McIntyre, ingo@. Fallout will be treated
case-by-case.
I had to clear out some regressions that were testing against groff's
stranger behaviours: these will now break, as we don't care about such
invocations.
Also removed the newline for `Cd' invocation in a non-SYNOPSIS context.
