 Here's another one that we have to do before the 0.2.7.2-alpha release if
 we're going to do it at all:

 https://github.com/trevp/tswip/blob/master/curve25519sigs.md

 I'm not in love with the differences here, but they seem mostly harmless.
 Trevor tells me that there's a chance of his that format being
 standardized.  If so, we might as well help it along by doing what they
 do.

 Changing the nonce-generation mechanism is IMO not very important.  The
 change to consider before the next alpha would be the signature format.
