Reinstating windows state after ediff

[Chris Stork]

Sometimes I split my frames in different ways into windows.  Always 
after I use ediff this window state is lost.

It seems that I have to find/write appropriate functions to add to 
ediff-{before,after}-setup-window-hook.  Has anybody done something like 
this already?

(Maybe it's a good idea to open a new frame for the two compared files 
and then (optionally) destroy it after ediff is done.  Pro: it does not 
even touch any of the other frames.  Con: it does not work on a 
terminal, which is fine for my puposes.)

Thanks,
Chris
