[PATCH] Diff overhaul, adding the other half of copy detection.
This patch extends diff-cache and diff-files to report the unmodified files to diff-core as well when -C (copy detection) is in effect, so that the unmodified files can also be used as the source candidates. The existing test t4003 has been extended to cover this case. Signed-off-by: NJunio C Hamano <junkio@cox.net> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>
