The latter literally was \"rev-list HEAD | git diff-tree --stdin\".\n\nGiving a commit on the command line and giving one from the stdin was made\nconsistent. IOW, \"rev-list HEAD | xargs -n1 git diff-tree\" would give you\na similar output.\n"},{"id":"118983","messageId":"7vhbww5yxb.fsf@alter.siamese.dyndns.org","threadId":"20250","inReplyTo":"87prbl8ay5.fsf_-_@krank.kagedal.org","subject":"Re: [PATCH] Update the documentation of the raw diff output format","fromName":"Junio C Hamano","fromEmail":"gitster@pobox.com","sentAt":"2009-07-28T20:34:56Z","receivedAt":"2009-07-28T20:34:56Z","isPatch":true,"sender":{"key":"gitster@pobox.com","avatar":"https://avatars.githubusercontent.com/u/54884?v=4"},"body":"Looks reasonable; thanks.\n"},{"id":"119016","messageId":"873a8grpay.fsf@krank.kagedal.org","threadId":"20250","inReplyTo":"7vhbww5yxb.fsf@alter.siamese.dyndns.org","subject":"Re: [PATCH] Update the documentation of the raw diff output format","fromName":"David Kågedal","fromEmail":"davidk@lysator.liu.se","sentAt":"2009-07-29T06:11:49Z","receivedAt":"2009-07-29T06:11:49Z","isPatch":true,"sender":{"key":"davidk@lysator.liu.se","avatar":"https://avatars.githubusercontent.com/u/60530?v=4"},"body":"Junio C Hamano writes:\n\n> Looks reasonable; thanks.\n\nGreat.
