[bug #57594] sync hyphenation pattern files with TeX versions

[G. Branden Robinson]

Follow-up Comment #5, bug #57594 (project groff):


[comment #3 comment #3:]
> We should also write script(s) to verify the groff-cleanliness of the
hyphenation files.  This can easily take the form of one or more regression
tests like the 48 others we have.  The most obvious thing I can think of to do
is to have one test file for each supported groff locale which then calls .hla
(or uses my in-development internationalization patch, bug #59814).  If my
understanding is correct, an otherwise empty groff document will suffice to
provoke diagnostics from .hla if the hyphenation or exception files contain
unsupported constructs.  See src/roff/troff/env.cpp:hyphen_trie::hpf_getc and
src/roff/troff/env.cpp:hyphen_trie::read_patterns_file.

The foregoing is done.

    [tests]: Test localization with `-m` option.
    
    * src/roff/groff/tests/initialization_is_quiet.sh:
    * src/roff/groff/tests/localization_works.sh: Rewrite test to use
      explicit macro file loading localization mechanism.


I haven't updated FOR-RELEASE yet because we're blocked on UTF-8 input
handling as noted in my previous comment, and the process is not streamlined
enough to become robotic.  I had to manually do some tomfoolery to deal with
our English hyphenation exceptions file (on the bright side, it's much shorter
now).
