[EM] Complete sincere Nash equilibria test posting

[Michael Ossipoff]

I left a few words out of this posting, so I'm re-posting it in more 
complete form:

Juho--

I told you this:

With wv, when there's a CW, there's always a Nash equilibrium in which the
CW wins and no one reverses a preference.

With margins, there are situations in which the only Nash equilibria are
ones that involve order-reversal, even when there's a CW.

How does that make you feel about margins?
