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.
Feedback and OK kristaps@; Joerg Sonnenberger (NetBSD) and
Sascha Wildner (DragonFly BSD) agree with the general direction.

roff_getstr() family of functions into roff.c with the "first_string"
directly in struct roff. Second, pre-process each line for reserved
words in libroff, splicing and re-running a line if it has one (this
allows defined symbols to be macros). Remove term.c's invocation of the
roff_getstrn() function. Removed function documentation in roff.3 and
added roff.7 `ds' documentation.

passed in to libmdoc and libman.
Fix mdoc.3 and man.3 EXAMPLE sections to include regset.
Add MDOC_SYNPRETTY flag cueing front-end to nicely format certain values
as if SEC_SYNOPSIS were the current section.

functionality and UGLY works quite well thanks to schwarze@'s careful
attention.
This also backs out function-prototype changes for struct regset,
instead stuffing a pointer to the regset directly into struct
mdoc/man/roff.

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.

stringified in main.c.
Allow `An' to handle an argument and child (with a warning).
Allow `Rv' and `Ex' to work without a prior `Nm' as groff does (with a
warning).
Allow inconsistent column syntax to only raise a warning.

Prompted by Ingo and Claus Assman, added warn/ignore for text lines beginning with `\."'.

Added title-case check for (libman).
Fixed premature closure of roff instruction scope (libman).
Added documentation of ignored roff macros to man(3).

friends (much simpler).
Split blk_imp() into blk_exp() (explicit macros), blk_dotted() (roff macros), and the original.
Added de, dei, am, ami, and ig roff macros (for now, these are discarded within the parse).

Clean-ups, better documentation in man_hash.c.
Added extra space for "." in man_hash.c (unused for the time being).

Consolidated node unlinking in -man.
Conclude nested next-line scope issues noted by Ingo Schwarze.

next-line scope extensions possible). man.7 reflects block and line scoping,
and also includes a REFERENCE section that will be used as a template for the
big mdoc reference. Many fixes in next-line behaviour for both inline and
block macros. Added some macros for compatibility (from me.7). Corrected
quoted-literal handling for libman.

Added `\c' to known escapes (only used in man, but still).

libman supports MAN_IGN_ESCAPE (like MDOC_IGN_ESCAPE).
All popular escapes now handled consistently.

Added STRUCTURE section to mdoc.7, too.
