[troff]: Fix Savannah #63142 (newlines as delims).
Withdraw support for newlines as escape sequence delimiters. Only a few
(6) supported this, and the rationale behind it is unknown. DWB 3.3
troff didn't behave this way in any case.
* src/roff/troff/input.cpp (do_overstrike, do_bracket, do_name_test)
(do_zero_width_output, do_width, do_device_control): Do it. As a
bonus, check starting delimters for these escape sequences
(`\[obAZwX]`) for validity in general.
(do_overstrike, do_bracket, do_zero_width_output): When returning
early, delete the `new` node we just allocated to avoid leaking
memory.
(token:next): Be prepared for the `\b` and `\o` escape sequences
to return a null pointer (if the sequence doesn't even validly
get off the ground), as `\Z` and `\X` already do.
* src/roff/groff/tests/some_escapes_accept_newline_delimiters.sh:
Delete.
* src/roff/groff/groff.am (groff_TESTS): Drop test.
* doc/groff.texi.in (Delimiters):
* man/groff.7.man (Delimiters):
* NEWS: De-document support for newlines as delimiters.
