From: Junio C Hamano Date: Tue, 15 Nov 2005 01:53:22 +0000 (-0800) Subject: diff: --full-index X-Git-Tag: v0.99.9k~3^2~4 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=80b1e511d74ac2942043f912d850cb6b85b44689;p=git.git 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.
