Since C-u is now a completely normal command, the C-u that precedes is
treated the same as any other command that might have been run before.
IOW, the C-u should never be included.

I'm not sure which change you're referring to.  AFAIK (and according to
this bug report) the change has already been done (tho not to the
docstring).
