I was being too vague here.  You made what looks like a reasonable
change but it is to a low-level function which is called by more than
one place.  I was hoping that, since you wanted to see this fixed, you
might also be willing to make sure that your change doesn't break
anything else.  But, I didn't say that so, my bad.

I've checked in a modified version of your patch along with a ChangeLog.
