Redex also has something like this built into the 'stepper' function.
I struggled with getting that right (altho a lot of those struggles
were because I was using pretty-print to produce the results) so if
this is better, that'd be nice to use instead.

Anyways, if you want to try it out, define a reduction system that
reduces from one of the sexps to the other and then use the stepper so
those two expressions come out as subsequent steps.
