Do I understand correctly that the tip of your branch is a unit test for
the problem, and the previous commit is the conditional revert? (As in:
it re-introduces the previously existing behavior without introducing
the mentioned Coverity problem again.) If so, I think that's fine to
have, but please don't pick the revert as-is to master, i.e. instead of
introducing that #if 0 code, just remove the code that would be
disabled. I'm afraid I don't know more about the SwDoc::AppendDoc() code
than you. :-)
