[PATCH] Implement git-checkout-cache -u to update stat information in the cache.
With -u flag, git-checkout-cache picks up the stat information from newly created file and updates the cache. This removes the need to run git-update-cache --refresh immediately after running git-checkout-cache. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
