Comment:

 I am risk-averse and don't think we should merge this until we're ready to
 actually send IPv6 link specifiers. Because I don't know if this patch
 helps with bugs where we accidentally send IPv6 extends. And we can't
 really test it.

 ln5 is working on a proposal for IPv6 extends, so we should be able to
 merge this in 0.3.5 or 0.3.6.
