The first specific mention of moving directories in Research is in
v10, but I'm sure that was implemented considerably earlier. The only
things special about moving a directory were that it needed root
privilege and checked against moving a directory into itself. As with
ordinary files, copying (with loss of hard links) happened only when
moving between different file systems. As far as I know, no atomicity
precautions were taken.
