[nroff]: Fix Savannah #60943.
* src/roff/nroff/nroff.sh: Add new `is_option_argument_pending` flag to
add an additional state to the option parser. Set it if an
argument-requiring option is encountered with no abutting argument.
If it is set when a new argument is encountered, absorb the argument
into the groff option list and clear the flag. Moderize script in a
couple of other ways.
- Exit with status 2 upon usage errors so that this is
condition is easily distinguished form a groff abort (which
exits with status 1).
- Test shell variables for non-nullity with test(1) -n operator
instead of a string comparison.
* src/roff/nroff/tests/verbose_option_works.sh: Test correct
construction of groff command using this input form.
* src/roff/nroff/nroff.1.man (Options): Add spaces between option flags
and option arguments. Sync metasyntactic variable names with groff(1)
while we're at it.
(Description): Drop sentence warning of whitespace prohibition.
(Exit status): Add new section.
* NEWS: Add item since the interface changed.
