Committed, thanks.  It's rather embarrassing that I didn't notice this
problem, because I did compare that logic with the preceding loop.  I
concluded it was OK on the theory the previous loop would have already
given up if there were no partial plans.  But that's wrong, of course:
the previous loop will not have given up if it grabbed the last plan
in a list of only non-partial plans.  Oops.
