git-init: set core.worktree if GIT_WORK_TREE is specified
Now you can do the following to create a repository which
has a separate working tree:
/tmp/foo$ export GIT_DIR=/tmp/bar
/tmp/foo$ git --work-tree . init
Initialized empty Git repository in /tmp/bar/
/tmp/foo$ git config core.worktree
/tmp/foo
