It looks like current-frame-configuration returns a list of all frames
with parameters and window configurations for each of them.  I'd
prefer to just save and restore state of the one frame that was
selected when I started Ediff.

Is there a reason that the code I have *shouldn't* work (besides the
fact that it doesn't)?  I.e., is there a gap in my understanding?
