diff -B -M: fix output for "copy and then rewrite" case
Starting from a single file, A, if you create B as a copy of A (and possibly make some edit) and then make extensive change to A, you will see: $ git diff -C --name-status C89 A B M A which is expected. However, if you ask the same question in a different way, you see this: $ git diff -B -M --name-status R89 A B M100 A telling us that A was rename-edited into B (as if "A will no longer exist as the result") and at the same time A itself was extensively edited. In this case, because the resulting tree still does have file A (even if it has contents vastly different from the original), we should use "C"opy, not "R"ename, to avoid hinting that A somehow goes away. Two existing tests were depending on the wrong behaviour, and fixed. Signed-off-by: Junio C Hamano <gitster@pobox.com>
