Given one existing commit, revert the change the patch introduces, and record a new commit that records it. This requires your working tree to be clean (no modifications from the HEAD commit). This is based on what Linus posted to the list, with enhancements he suggested, including the use of -M to attempt reverting renames. Signed-off-by: Junio C Hamano <junkio@cox.net>

# Define MOZILLA_SHA1 environment variable when running make to make use of

# a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
