It does with limited testing, but having it in the arith_driver like
that means the argument list gets unnecessarily scanned for floats when
there are 2 arguments.
Here's a patch to put the change in the DEFUN. Note that there is no
effective change for the two arg form, so its still efficient and there
wont be any "surprises" for the dominant usage.
