[groff] 01/01: Add another regression test for case transforms.

[G. Branden Robinson]

gbranden pushed a commit to branch master
in repository groff.

commit 8f1f2938481303f2a2ae1234427c434af02cd1ff
Author: G. Branden Robinson <address@hidden>
Date:   Mon Sep 9 03:09:23 2019 +1000

    Add another regression test for case transforms.
    
    Add regression test to check behavior of case transformation request on
    a string containing a Unicode character escape.  Right now, this is not
    supported, so it is an XFAIL test in the parlance of DejaGNU/POSIX
    1003.3.
    
    * src/roff/groff/tests/string_case_xform_unicode_escape.sh: New test.
    * src/roff/groff/groff.am: Run the test.
