If I understand correctly, while it's true that the 'link' file will inhibit pruning, don't we still have the problem that "git worktree list" will show an outdated path if the user fails to update 'gitdir'? And doesn't the "branch already checked out in some other worktree" interrogation also depend upon 'gitdir' being up-to-date? -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
