ZNC - Advanced IRC Bouncer

According to the IRC spec, for all messages, including PASS, the last parameter can be prefixed with a colon, allowing spaces in that parameter. ZNC does not handle a PASS message where the password argument is prefixed with a colon. And here's the fix:

Client.cpp, line 90:
m_sPass = sLine.Token(1);
if (m_sPass.Left(1) == ":") {
m_sPass.LeftChomp();
}
