[troff]: Fix Savannah #67744.
* src/roff/troff/input.cpp (read_delimited_name): Stop accepting
horizontal motion tokens as escape sequence delimiters. This to
prohibit use of the delimited `\h` escape sequence as a delimiter, but
because of GNU troff's internal design, also prohibits the
parameterless `\0`, `\^`, and `\|` delimiters.
* doc/groff.texi.in (Delimiters):
* man/groff.7.man (Delimiters): De-document support for these
delimiters.
* NEWS: Report change.
Fixes <https://savannah.gnu.org/bugs/?67744>. The problem of acceptance
of `\h` as an escape sequence delimiter appears to date back to groff's
birth. (`get_delim_name()` didn't check for any token types except EOF
and newline.)
