Sorry, it's been crazy busy and there were other fixes I really needed
to get upstream.

If it really is superfluous, the compiler will optimize it away.  I
have been bitten more times than I can count with fuzz testers and C's
_fine_ signed vs. unsigned integer semantics.  So I prefer to be
careful here.

If we can really be sure it's safe, we can always remove the extra
comparison in a separate patch, since that's unrelated to the real bug
we're trying to fix.
