Oh yes I forgot to point this out. With this approach we have to have
an id, and the directory name inside $GIT_DIR/worktrees seems a
natural choice. I was hoping to go with extended ref syntax instead
[1] which gives us more flexibility in identifying a worktree. But I
don't think that's going to happen. "git worktree" would need some
improvements to show this id, specify it at "git worktree add" and
potentially rename it even.
