There are numerous issues with the ParseLine() function, eg.

• No distinction is made between nick and user tokens in the prefix, you've simply called 'nick' 'user' and then not parsed the actual user token.
• A nick prefix can exist without user and host tokens supplied as simply ":nick CMD etc"
• The parser applies little to no restrictions on characters within tokens.

And various others. Although it may "appear to work" I suggest (re)reading http://tools.ietf.org/html/rfc2812#section-2.3.1 and implementing the grammar completely as this will break should a server decide to do anything "weird".
