pack-redundant: document deprecation

Running the command itself has generated a warning for several versions, which has recently been upgraded to an error. Let's also make sure the documentation mentions what is going on. This also gives us a good spot to explain the reasoning and recommend alternatives. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

14 +WARNING
15 +-------
16 +`git pack-redundant` has been deprecated and is scheduled for removal in
17 +a future version of Git. Because it can only remove entire duplicate
18 +packs and not individual duplicate objects, it is generally not a useful
19 +tool for reducing repository size. You are better off using `git gc` to
20 +do so, which will put objects into a new pack, removing duplicates.
21 +
22 +Running `pack-redundant` without the `--i-still-use-this` flag will fail
23 +in this release. If you believe you have a use case for which
24 +`pack-redundant` is better suited and oppose this removal, please
25 +contact the Git mailing list at git@vger.kernel.org. More information
26 +about the list is available at https://git-scm.com/community.
