Oh I see, I missed that it did actually have quotes for the mv.  Yeah the
echo doesn't matter.

I do wonder if it would work if you had two spaces in a row.  I suspect
it would compact multispace to one space.  Probably would convert tabs
to spaces too.  Probably not a common case, but hey gotta make sure it
is perfect.

It's a handy tool that comes with perl I believe.  So the regex is
