[PATCH] git-apply: implement --summary option.
Typical expected usage is "git-apply --stat --summary" to show diffstat plus dense description of information available in git extended headers, such as creations, renames, and mode changes. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
