* @brief Parse the channel names into links.

* RFC 1459 parsing:
* <channel> ::= ('#' | '&') <chstring>
* <chstring> ::= <any 8bit code except SPACE, BELL, NUL, CR, LF and comma (',')>
*
* We ignore &channels (local channels) since & is commonly used in text, and we do not
* consider channels with quotes in their name since it will mess up linking.
*
* Valid channel names are converted into irc://(account host)/(channel name)
