The "mini-CVS" you mention can be done just by using RCS commands on a file.
(info rcsintro, or man rcs) We could implement a backup which contains every
change ever made simply by using an RCS file in addition to the standard ~
(last save). So at every given interval (or when the user hits save), the
current text would "ci" and update the RCS file. This would be preferable to
having four or five additional files as backups IMHO.

Might also be kinda kewl to have a ui slider to roll back through all
previous changes.
