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.

so that everybody can use them. This follows the convention of
libXXXX.h being internal to a library and XXXX.h being the external
interface. Not only does this allow the removal of lots of redundant
NULL-checking code, it also sets the tone for adding new mandoc-global
routines.

Don't use it in new manuals, it is inherently non-portable, but we
need it for backward-compatibility with existing manuals, for example
in Xenocara driver pages.

error-class messages when data is being ignored by specifying it in "^"
cells (either as-is or in blocks).
Also note again that horizontal spanners aren't really supported...

sure signedness is correct. Verify that layouts MUST exit for data

always hold, which cleans up the table stuff a bit.
Second, set a "spans" value per data cell consisting of the number of
skipped TBL_CELL_SPAN layout cells.
Third, make tbl_term.c understand how to skip over spanned sections when
iterating over the header queue.
What remains is to calculate the widths of spanned cells.

(isn't now, but will need to be, used by -T[x]html also). Necessitated
a lot of churn in getting tbl_calc* code out of tbl_term.c and into
out.c, including renaming some structures and so on. The abstraction is
in having a pointer to a wrapper function for calculating string widths.
The char devices use term_strlen and term_len; the others will probably
just use strlen().
While at it, remove some superfluous assertions in the tbl code. This
allows all tbl manuals to clear.
Lastly, set the right-margin to be the maximum margin for each table
span. This allows big, complicated tbl-pages like terminfo to be
displayed. They're ugly, but they work.

should be printing the contents, but for the time being, this is good
enough.

definitely not general, but it's good enough for pod2man definitions
(after I clean up the roff, which will be addressed in later fixes).

Also made sign-less \s-style escapes be ok (this is technically against
what's in the groff.7 manual, but seems pretty widespread). Noted by
Thomas Jeunet as uglifying the gcc.1 manual.

single-character escape (and ONLY this type of escape) will map back
into itself:
"If a backslash is followed by a character that does not
constitute a defined escape sequence the backslash is silently
ignored and the character maps to itself."

was completely unmaintainable. The new one is both readable and quite
similar to mandoc_special(), which in future versions will easily allow
throwing-away of unsupported escapes (such as \m). It's also a fair bit
smaller.
DECO_SIZE has been removed: this crap, like colours, will not be
supported.
mandoc_special() also has #if 0'd switch branches for ALL groff.7
escapes and some lint fixes.

unclear about which units accept floats/integers, which leads me to
assume that it handles either and rounds as appropriate.
