------------------------------+---------------------------------
 There appears to be a bug in Tor's IPv6 Exit code, where exits that have
 IPv6Exit set do not have an ipv6-policy line in their descriptor.

 To assist in diagnosing this bug, we should log a warning message (not a
 bug message) containing the full exit policy, when the IPv6 exit policy
 summary is empty, but IPv6Exit is 1 and ExitRelay is 1 or auto.
