[rant] Should reverting a buffer really discard undo history?

This sounds like a work-around.  Why isn't "revert" an undoable operation?  
Maybe it would cost too much RAM when reverting a 64 MB file, but for typical 
files on today's computers we can afford to treat the entire buffer text as 
having been replaced.

Nor can you use it to define your own functions that will be bound to keys.  
Nor can it deal with conditional code in your .emacs dealing with platforms 
other than the one you're using at the moment.
