Avoid "diff-index --cached" optimization under --find-copies-harder
When find-copies-harder is in effect, the diff frontends are expected to feed all paths, not just changed paths, to the diffcore, so that copy sources can be picked up. In such a case, not descending into subtrees using the cache-tree information is simply wrong. Signed-off-by: Junio C Hamano <gitster@pobox.com>
