No, both C-u 3 and M-3 will set the prefix argument to 3, so commands
cannot distinguish between them.  I know I suggested the numeric vs
non-numeric thing, but I think I was just confused about it.
Non-numeric arguments are only good for a single toggle (increment vs no
increment), not control over a amount (increment by X).  And you can't
express both at once (both increment and repeat).
