The current update_linked_gitdir() has a bug that can create "gitdir"
file in non-multi-worktree setup. Instead of fixing this, we step back a
bit. The original design was probably not well thought out. For now, if
the user manually moves a worktree, they have to fix up "gitdir" file
manually or the worktree will get pruned. In future, we probably will
add "git worktree mv" to support this use case.
