I checked what POSIX, who does give "-p" to mkdir(1), has with
mv(1), and they do not have "-p".  Neither GNU, which tends to add
such "usability" enhancements on top of what everybody else has.

And I think they are being very sensible.  By not adding such an
option to "mv", they can sidestep the unnecessary ambiguity, and it
isn't too bad to do a "mkdir -p" separately before doing such a "mv"
into a (potential) new directory.

So, let's not do this patch.

Thanks.
