Tor should mandatory require brackets around ipv6 address
Stem and Tor do differ about validating an ipv6 address :
ValueError: '2a00:1450:4001:0058::7/16' isn't a wildcard, IPv4, or IPv6 address: reject6 2a00:1450:4001:0058::7/16:443
The same term is accepted by Tor (within torrc).
maybe Tor should be more strict too ?
A short talk with atagar on IRC yielded into this bug report.
