This is my fault since I suggested this rewrite[1], but other documentation calls this <id>, not <tag>, so: s/tag/id/ (Again, not worth a re-roll; perhaps Junio can tweak it when queuing.) > "git worktree move" has come so we don't really need this, but since > it's easy to do, perhaps we could keep supporting manual worktree move > a bit longer.
