Well, this command reverts the current buffer back to the state when it 
was last checked out. Which can be handy, but is not what I am looking 
for. Let me take another stab at explaining. I have a document that has 
gone through these changes (numbers are version numbers):

1.5
Bob went to school

1.6 
Mary went home

1.7
John went to the market

1.8
Chris discovers emacs (and then fire)


I open the document (1.8) and discover that I need to go back to version 
1.6. How best to do this? I can open 1.6 up using the show-other-version 
command, but then I have to select everything in the old display document 
and paste it "over" the new document. It just seemed to me there must be 
a better way of going back more than one revision.

Maybe I am just missing something really stupid... or maybe this is just 
not needed very often. But the ability to revert back more than one 
version seems very useful to me.
