The recent rewrite broke "git-whatchanged -v -p drivers/usb/" but "git-whatchanged -v -p drivers/usb" still works. Just strip out the trailing slashes internally to make it work again. It uses compare-thing-with-number comparison order instead of visual comparison order ;-). Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
