[troff]: Fix Savannah #68521.
* src/roff/troff/input.cpp (token::next): Perform range check on
parameter to `\N` escape sequence; throw error diagnostic if it fails.
Fixes <https://savannah.gnu.org/bugs/?68521>. Problem introduced by me
in commit b039f8c3d1, 2025-03-29, an attempt to improve compatibility
with DWB troff. (But as noted in that commit, DWB troff appears not to
_exercise_ its freedom to employ negative character indices.)
