This is exactly how the Lisa worked.  The Desktop Manager would send 
applications a suspend request, when the user hit the soft power off 
switch or ejected the diskette containing a document.

To suspend a document the application would write out the entire state 
pertaining to that document (including scroll position, selection, etc.) 
into a separate suspend file.  The last saved version of the document was 
untouched.  

The next time you opened that document, everything would be as it was when 
suspended.  You could choose Undo, or Revert, etc.
