Subject: Make GIT_INDEX_FILE apply to git-commit
X-Git-Tag: v1.5.3.7~10^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=859a4dbcadd200ae955fe36d0c4fb3f4bce0e032;p=git.git

Make GIT_INDEX_FILE apply to git-commit

Currently, when committing, git-commit ignore the value of
GIT_INDEX_FILE, and always use $GIT_DIR/index. This patch
fix it.
