[PATCH 35/42] rev-parse: prints --git-dir relative to user's cwd

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

git-rev-parse.txt does not say much about this. But I'm sure
git-sh-setup.sh wants "git rev-parse --git-dir" be relative to user's
cwd.

git_dir variable in environment.c on the other hand is relative to
git's cwd, not user's cwd. Convert the relative path (actualy by making it
absolute path) before printing out.
