#6146: Incorrect IRC protocol when connecting to localhost

Priority:  minor   |   Component:  unclassified

-------------------+--------------------------------------------------------
 When connecting to an irc server running on localhost where ipv6 is
 enabled, pidgin sends invalid IRC protocol messages for the USER command,
 which prevents the connection.

 For example:

 Sun Jun 22 00:14:21 2008: New file descriptor: 7
 Sun Jun 22 00:14:21 2008: C[7] -> :7-unknown PASS s3cred
 Sun Jun 22 00:14:21 2008: C[7] -> :7-unknown USER xHire LinuxTop ::1
 :xHire
 Sun Jun 22 00:14:21 2008: C[7] -> :7-unknown NICK xHire
 Sun Jun 22 00:14:52 2008: Remove file descriptor: 7

 Note here the USER command's third parameter, ::1 starts with a :, so the
 ircd interprets this to mean a command with three parameters, the third
 parameter being ":1 :xHire". There are several fixes for this, the first
 being not using the field (recommended by the RFC) and putting a * here,
 the second being to enclose the hostname/ip in quotes, and the third to
 place a 0 on the start of all ipv6 addresses that start with a : (most
 ircds do something like this for representing ipv6 in whois etc).

 I'll leave the implementation details to you :)
