Sorry, I got quite confused... I was picturing os.rmdir() as
having the shutil.rmtree() functionality, and you suggesting
that os.remove() should be doing the same...  no idea where I got that.

Next time I'll try to wake up a little more before posting... :-)

Hmmm... might there not be code which uses os.remove() with the
assumption it is not going to remove anything which is an empty
directory?  Maybe this is just the reinterpretation of the direction
I was going, after correcting my confusion.  I suspect any change
to the behaviour of these functions could lead to a situation
where existing code behaves very badly.
