I'm sorry, I don't want to spend more time on such a minor issue.  The
patch is simple and yields good benefits, and Victor seems to have
approved it, so I'm inclined to ignore your skepticism and commit.

I would have liked more constructive criticism (perhaps the patch is
inefficient or suboptimal, etc.), but it seems I'll have to do without
it.
