[tor-relays] empty exit policy if ipv6 address is not surrounded by [..]

[Damian Johnson]

Thanks Toralf. Took a quick peek but this is gonna require more
thought. Tor's IPv6 addrspec states that policies should have
brackets...

https://gitweb.torproject.org/torspec.git/tree/dir-spec.txt#n1282

... but the torrc is looser...

https://www.torproject.org/docs/tor-manual.html.en#ExitPolicy

Stem accounts for this by adding brackets when reading from a torrc
file, but requiring them from other spots through the control port. So
question is 'how is nyx fetching this?'. If its coming from certain
control port commands then this is a tor bug, whereas with other spots
it's a stem or nyx bug.

Regardless, please file a ticket for this with actual torrc lines that
reproduce the issue...
