Subject: Simplify setup of $GIT_DIR in git-sh-setup.sh
X-Git-Tag: v1.5.5-rc0~192
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=4d6d6d2d3f778b892f2481969e530ff67ee0aa6c;p=git.git

Simplify setup of $GIT_DIR in git-sh-setup.sh

Using 'git rev-parse --git-dir' makes the code shorter and more future-
proof.
