Comment (by teor):

 Now that I think about it, relays may have only ever been able to exclude
 their fingerprint from MyFamily once they had a consensus with their own
 descriptor in it.

 So the first descriptor from a relay would always contain its fingerprint
 in MyFamily, then subsequent descriptors wouldn't, unless the relay was
 offline.

 If this is the case, then you won't find anything using `git bisect`. Try
 modifying router_build_fresh_descriptor like I suggested in the previous
 comment, and writing a unit test (you might find it easier to write a unit
 test if you refactor the code that sets the family line into its own
 helper function), and see if that works.
