[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.
