diff: --full-index
A new option, --full-index, is introduced to diff family. This causes the full object name of pre- and post-images to appear on the index line of patch formatted output, to be used in conjunction with --allow-binary-replacement option of git-apply. Signed-off-by: Junio C Hamano <junkio@cox.net>
