[groff]: Accommodate macOS od behavior in test.
* src/roff/groff/tests/some_escapes_accept_newline_delimiters.sh: Weaken
regexes in two test cases to accommodate excessive output from macOS's
'od' command. Resolves test failure seen on macOS.
* HACKING: Add section "Writing Tests" and document the above since this
is the second time I've cracked my shin on this.
* ANNOUNCE: Drop notice of failing test case, now resolved.
