[groff] 11/18: [groff]: Add regression test for Savannah #61748.

[G. Branden Robinson]

gbranden pushed a commit to branch master
in repository groff.

commit 525fe85ec9de643999e44a77568d66a7913b77b1
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Sun Jan 2 00:25:36 2022 +1100

    [groff]: Add regression test for Savannah #61748.
    
    * src/roff/groff/tests/html_works_with_grn_and_eqn.sh: Do it.
    * src/roff/groff/groff.am (groff_TESTS): Run it.
    
    Test may loop infinitely at this commit; since the behavior depends on
    a read from uninitialized memory, I doubt that it is deterministic
    across system configurations.
