Comment (by ahf):

 Found another bug with this code:

 {{{
 $ nc -l -p 6667
 CAP LS
 NICK user
 USER user user
 rxyw2yu2mxczblqcov5d3m6fqyem7rnamcean46wu7srdh5so7dro7qd.onion :Unknown
 PROXY TCP6 fc00:dead:beef:4dad::0:25 ::1 37 6667
 }}}

 This happens when an IRC client is connecting to an OS with this feature
 enabled. We need to make sure the `PROXY` string is added to the beginning
 of the buffer and not the end.
