for example used by groff_hdtbl(7) and groff_mom(7).
Also correctly interpolate arguments during nested macro execution
even after .shift and .return, implemented using a stack of argument
arrays.
Note that only read.c, but not roff.c can detect the end of a macro
execution, and the existence of .shift implies that arguments cannot
be interpolated up front, so unfortunately, this includes a partial
revert of roff.c rev. 1.209, moving argument interpolation back into
the function roff_res().

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.

Avoid the double redirection from -Tutf8 via -Tlocale to -Tascii.
Add LC_CTYPE to the ENVIRONMENT section.
While here, also correct a few inaccuracies and tweak some wordings.

Originally, naddy@ requested this in 2011 (or maybe even earlier).
It was discussed with joerg@, kristaps@, naddy@, and espie@ in 2011,
and everybody agreed in principle, but it was postponed because
kristaps@ wanted to do some cleanup of the message system first.
Meanwhile, message infrastructure was improved about a dozen times...
This makes long, tedious commands like "mandoc -Tlint *.1 2>&1 | less"
unnecessary and allows simple ones like "man -l -Tlint *.1".

or content to style suggestions.
Also upgrade two warnings that may cause information loss to errors.

in the base system, inspired by mdoclint(1).
We are able to do this because (1) the -mdoc parser, the -Tlint validator,
and the man(1) manual page lookup code are all in the same program
and (2) the mandoc.db(5) database format allows fast lookup.
Feedback from, previous versions tested by, and OK jmc@.
A few features will be added to this in the tree, step by step.

I'm using a very simple, linear time / zero space fuzzy string
matching heuristic rather than a full Levenshtein metric, to keep
the code both simple and fast.

-Wopenbsd and -Wnetbsd to check conventions for the base system of
a specific operating system. Mark operating system specific messages
with "(OpenBSD)" at the end.
Please use just "-Tlint" to check base system manuals (defaulting
to -Wall, which is now -Wbase), but prefer "-Tlint -Wstyle" for the
manuals of portable software projects you maintain that are not
part of OpenBSD base, to avoid bogus recommendations about base
system conventions that do not apply.
Issue originally reported by semarie@, solution using
an idea from tedu@, discussed with jmc@ and jca@.

We provide users with tools. We don't attempt to prevent them from
using them in stupid ways: depending on the context, not every
stupid-looking use is necessarily actually stupid, and not every
stupidity can be automatically detected anyway, so don't even try.

It has been obsolete for more than two years.
Use -T html.

and delete an example showing the arcane -W stop option.

Switch -W all from meaning -W warning to meaning -W style.
The meaning of -T lint does *not* change, it still implies -W warning.
No messages on the new level yet, but they will come.
Usually, i do not lightly make the user interface larger.
But this has been planned for years, and EXIT STATUS 1
was reserved for it all the time. The message system
is now stable enough to finally implement it.

As observed by Jan Stary <hans at stare dot cz>, this is useful such
that after 'alias man="man -m $HOME/man"', 'man -l foo.1' still works.
Simplify and shorten the description of -m, and use .Ic for macros.

but even the CommonMark specification doesn't require parsers
to support that, so portability would be doubtful.
While here, provide a link to the CommonMark specification.
