[PATCH] Perform clone in place -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [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. manifest hash: cf7cf24f8fa1120b609b0beee4281bc236e484c0 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCwxxJywK+sNU5EO8RAjnlAJ44B1jhFvuYF3uNDH6qWDKaqgURuwCdFeFo Y9tjLx6TLCBWT146h21YEGA= =E1n/ -----END PGP SIGNATURE-----
