[net.emacs] file versions

kgk%brown.csnet@CSNET-RELAY.ARPA (10/26/85)

From: Keiji Kanazawa <kgk%brown.csnet@CSNET-RELAY.ARPA>

Where were file versions implemented? Are they in a patch? I only
joined this mailing list recently, so I've missed the early patches
to 16.60. Could somebody mail me a diff from vanilla 16.60 to
current for files.el?

Thanks
