This changes the diff-raw format again, following the mailing list discussion. The new format explicitly expresses which one is a rename and which one is a copy. The documentation and tests are updated to match this change. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
