diff: deprecate -q option to diff-filesjc/diff-filter-negation
This reimplements the ancient "-q" option to "git diff-files" that was inherited from "show-diff -q" in terms of "--diff-filter=d". We will be deprecating the "-q" option, so let's issue a warning when we do so. Incidentally this also tentatively fixes "git diff --no-index" to honor "-q" and hide deletions; the use will get the same warning. We should remove the support for "-q" in a future version but it is not that urgent. Signed-off-by: Junio C Hamano <gitster@pobox.com>
