There is definitely no particular urgency to this change.

Since these functions don't perform anything complex and aren't updated
regularly, my main goal was to remove unnecessary (at the moment) checks
and fix up their somewhat misleading descriptions. Cleaning up, in other
words. But I understand your point of view.

If you don't think this patch is warranted at this point, I totally
understand.

I added the 'Fixes:' tag mostly as a requirement for patch's
description. Once again, it doesn't "fix" anything broken as much as it
cleans up stuff.
