    See it from the users point of view. Is it not desireable then to be 
    able to undo all changes that will be saved to disk?

The argument seems powerful, but it would seem to apply just as
strongly to set-visited-file-name.  Do you think set-visited-file-name
should be an undoable buffer change?
