Summary: distinct error type from shutil.move()

Initial Comment:
I need to call shutil.move() and be able to tell the
difference between an error such as access denied and
an error due to the two arguments being the same file.

Dear Pythonistas: please apply this patch.  There is no reason not to, and
it enables programmers to use shutil more cleanly.

I'm not sure how to draw attention to my patch, so I will
try assigning it to anthonybaxter.  That ought to get attention.

Please apply.  This patch is completely backwards-compatible
and makes possible some uses of shutil.move().
