Yeah, I gave two alternatives, but the third one could be

       test_expect_success 'git frotz on various versions' '
           (
             for revision in one two three
             do
                     echo "frotz $revision" >expect &&
                     git frotz "$revision" >actual &&
                     test_cmp expect actual || exit 1
             done 
           ) &&
           test something else
       '

Anyway, that existing rule is not what I added in the rough draft
under discussion.  To clarify it, we'd end up needing "unless A, B
or C" that may be too complex.  I dunno.

Thanks.
