When "fetch --depth=N" where N exceeds the longest chain of history in the source repo, usually we just send an "unshallow" line to the client so full history is obtained. When the source repo is shallow we need to make sure to "unshallow" the current shallow point _and_ "shallow" again when the commit reaches its shallow bottom in the source repo. This should fix both cases: large <N> and --unshallow. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
