More to the point, should I delete this answer? I went through the help center pretty thoroughly and searched on here on Meta and couldn't really find anything that answers that question.
The answer explains the situation pretty well, I think, so I won't reiterate it here. The additional issue is a minor one, and there's no way it could have been revealed on review.
Are answers on CR just for the code reviews themselves, and not for posting the resulting fixed code? If so, I'll delete the answer. Because if that's the case, then that answer doesn't really add anything to the site.
