I think the name should be sufficiently different from auto-save-mode so
that the modes can't be confused. auto-save-files-mode would be confusing,
because auto-save-mode also saves files. I think including the "visited"
word is useful here because it's the meaningful distinction between the
modes: one uses the visited file name, the other doesn't.

Done.
