Oh, I see. There's no real need to distinguish here, so the attached
patch removes the distinction. Note that this should NOT be applied
as-is, as I have not updated the assembly implementation for this;
Robert is going to clean-room this in C (which should take all of a
minute or so :-) ), and I hope he can deal with the bit-banging at the
same time.
