diff: --abbrev option
When I show transcripts to explain how something works, I often find myself hand-editing the diff-raw output to shorten various object names in the output. This adds --abbrev option to the diff family, which shortens diff-raw output and diff-tree commit id headers. Signed-off-by: Junio C Hamano <junkio@cox.net>
