Subject: git-diff: Introduce --index and deprecate --cached.
X-Git-Tag: v1.5.0-rc0~176
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=4c81c213a479e4aae0653a56ad6e8db5c31f019c;p=git.git

git-diff: Introduce --index and deprecate --cached.

'git diff --cached' still works, but its use is discouraged
in the documentation. 'git diff --index' does the same thing
and is consistent with how 'git apply --index' works.
