[groff] 03/04: [tests]: Add test for multi-lingual man(7) scenario.

[G. Branden Robinson]

gbranden pushed a commit to branch master
in repository groff.

commit 9d558b9e0fa335bb42243bd343b8e6bca63a076a
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Sat Apr 9 08:22:07 2022 +1000

    [tests]: Add test for multi-lingual man(7) scenario.
    
    * tmac/tests/localization-works.sh: Test two more cases.  Ensure that
      the 'trap bit' (hyphenation value 2, which has nothing to do with any
      language) is preserved when switching locales back from a CJK
      language, since those languages' modes unconditionally clear it.  We
      test Japanese and Chinese; we have no localization macro file for
      Korean at this time.
