The current progress code really just counts commits. This patch makes it count all objects, giving us a "total" count close to what a repack would show. This is nice when using "git gc", which will usually have just repacked the whole repo. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
