[EM] Don't ignore the margins.

Did you ever notice that great thoughts turn to crap once you 
hit "Send"? Maybe it's just me.

If one contest is decided by a margin of 60, and two other contests 
are decided by a margin of 4 each, only a net of 8 preferences would 
be overturned by reversing the two contests, whereas 60 preferences 
(net) would be overturned by reversing the one. I had neglected to 
consider the minority vote in those contests.

Still, choosing the smallest total margin to be the bottom of a cycle 
appears to be a good idea.

Sigh.
