 > Warren, your branch disappeared. Did you commit it?

 Ah, sorry, I should have commented here.  I decided that my fix wasn't the
 correct approach.  On the mailing list, Josef suggested that the
 calculations should be vectorized, and I think he's right--they can be
 modified to handle broadcasting in a natural way. But my "fix" didn't
 broadcast; in fact, it flattened the arguments, making it impossible to
 broadcast.  Since it was basically the wrong approach, I silently removed
 my branch.

 Making a broadcasting version is probably not a lot harder than what I
 did, but (if I recall correctly), it might result in an API change.
