You have to be in the particular worktree's gitdir for this to work. I there exists
worktrees/foo
worktrees/frotz
worktrees/bar
Which would we expore? The code above must be in foo, frotz, bar
The main worktree is found not from worktrees/*, but from the root of the gitdir.

We cannot get to this code if not inside the gitdir, and if the user set GIT_DIR and/or
GIT_WORK_TREE to do something clever, that either worked or the code already threw an
error. git, without GIT_WORK_TREE set, uses the current directory as the worktree, or the
parent directory containing .git. So, we must be inside the gitdir if this code path gets hit.
