I'm hesitant to fool with this post-RC, and we don't have "a couple of
days" to wait for a fix --- 8.4.0 is scheduled to wrap on Thursday.
However, I see that the first of these cases actually represents a
regression from 8.3 and before; existing releases get 2009-03-01 out
of it while 8.4 fails to. So it seems we'd better do something.
