 From Damian's results, it appears that my design as written above would
 break about 516 exits.  That's too many.

 We *could* go with a different result:
   * if ExitNode is 'auto' and you are a relay and have no exit policy set,
 then we behave as currently, but warn you that you are being an exit node,
 and you should set ExitNode 1 or 0.  In a later version, we make ExitNode
 off by default.
