Thank you for testing it.

Right.  It would be good to find a way to make all this consistent.
It's unfortunate that C-x v l and C-x v P were different to begin with.

Regarding your idea, how about 'C-x V V'?  It's easier to type, won't
clash with another command we might want to put on 'c', and feels a bit
like C-x 4 4, C-x 5 5 etc.  Though, to be honest, I'd prefer it if we
could come up with something involving multiple 'C-u'.
