Add support for git-worktree

Main reason we didn't previously support work trees was because we had
assumed that the `.git` directory was always located in the repository
root. With separate work trees, this is not necessarily the case.

Add support by using Git commands to fetch the location of the GIT_DIR
instead of trying to determine it ourself.
