Thanks.  Hmm - one kind of raw prefix arg you don't handle yet is `-`
which is synonymous for -1.  M-- C-x 5 u gives the not so nice error
message:

  Wrong type argument: number-or-marker-p, -

Oh, and, I think all explicit `error' calls in your patch could be made
`user-error's instead, WDYT?

Ok, fine with me.
