Comment (by nickm):

 Hrm, this turned out to be just a little tricker than I thought.

 You see, first I had thought I'd just omit the Ed key when it didn't
 reflect consensus.  Unfortunately, that would involve stripping it from a
 microdescriptor, and producing a microdescriptor that no authority had
 actually voted for.  Doing that isn't such a good idea.

 Instead, I am adding a "NoEdConsensus" flag that the authorities should
 produce whenever the consensus for a node does not enable the authorities
 to make a statement about its Ed25519 key.  See branch (and the
 corresponding torspec branch, 'ed25519_voting_again') for full details.
