Bingo.  Exactly what I suspected:

So much for:

RMS is not "many", but I think the point has been made.  If we allow `C-u'
pass-through then we should also allow users to turn it off.  The next question
is what the default value should be.  I'd vote for pass-through by default, but
I don't feel strongly about that.
