-T[x]html and -T{pdf,ps,ascii}. Reported by Jason McIntyre.

function, which was only called in one place anyway.

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."

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.

In particular, fixes terminfo(3) and mdoc.samples(7).

by a [functionless] clean-up in term_ps.c, but this makes the
appropriate changes to "enable" initial proportional-width functionality
in term.c and fixes some areas of term_ps.c that were causing errors.

in mdoc_term.c and man_term.c down into term.c. This is still not
implemented in term.c, although stubs for width calculations are in
place. From now on, offset, rmargin, and other layout variables are
abstract screen widths. They will resolve to the the familiar values
for -Tascii but -Tps will eventually use points instead of chars.

terminal_free() in favour of ps_free() and ascii_free(). Moved ps_*()
functions into term_ps.c so that they don't clutter up term.c.

the output engine. Prints, for this initial version, only monospace and
without font decorations. It's a start.

Breakable hyphens are cued in the back-ends (with ASCII_HYPH) and acted
upon in term.c or ignored in html.c.
Also cleaned up XML decl printing (no need for extra vars).

save the visual cursor position in term_flushln()
and use that to avoid multiple blank lines in nested lists while
still putting subsequent empty list tags each on their own line;

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.

This is the bsd.lv part of the main step to bring it back in sync.
At the same time, this prevents trailing whitespace in the output:
We delay writing blanks until we are sure printable characters follow.
This is achieved by
* remembering the end of the word instead of its length
* and not using vbl any longer for the control of line breaking
* such that vbl can sum up all kinds of white space
* before writing a word, printing all the blanks collected in vbl
* within the word, adding NBSP chars to vbl, then continuing with the word
* after the word, adding blanks to vbl, then starting the next word

bold and underline, we use a stack (no cascading, no double-font-mode).
Font modes with \f only affect the current stack point, as documented in
mdoc.7 and man.7. While -mdoc stacks fonts with embedded macros, -man
replaces them (the stack is always size 1). This works for all
invocations in supported systems' manual corpora to date. It doesn't
support groff's insanity with line-scoped \f as documented in mdoc.7.
