I'm still not convinced this is a rational coding style. It seems to me
that if you're just going to copy the epoch from peer_name to peer_name,
just assign the epoch to INVALID and be done with it. There's no need for
both the assignment added in this patch and the line after it.

Now, normally I'd say that this is fixing a bug and having to fix other
people's bad code shouldn't be your problem. But since you wrote both
lines, fixing it to make sense seems reasonable to me ;).
