To elaborate on this since one might wonder "but aren't these those
tests?". I think you mean if we shouldn't have a "test_must_fail" test
there that asserts that parsing the options will die with the default of
GIT_TEST_DISALLOW_ABBREVIATED_OPTIONS=true. Yeah, that makes sense, it's
currently a blind spot that we just assume will keep working.
