[PATCH] Perform clone in place

From: Bryan O'Sullivan <bos@serpentine.com>

This is a rewrite of one of my earlier clone cleanup patches.  This
patch only does one thing - make clone operate in place.  It depends on
safe-clone.patch.

Don't have clone use os.chdir.  Instead, do everything in place.
