Why do you want C-u to be equivalent to "C-u 0"?  That's inconsistent,
and you already provide an easy way of supplying zero: by using no
prefix argument at all.

In any case, what I meant was that the processing is incompletely
described by the documentation.  And the documentation about the
effect of the prefix argument should be in the doc strings of the
commands, not in the doc string of this function, which is not
intended for interactive use.
