    room: Highlight more nick variants
    
    We have been stripping trailing 'garbage' like trailing underscores since
    commit cc7042fa268c, which solved getting highlights for the regular nick
    after reconnecting as nick+'_'. However the nick is also used frequently
    to convey status - 'nick-away', 'nick|bbl', 'nick_office' - which is not
    covered by the current approach. To include those variants in highlighting,
    match up to the first non-alphanumeric character (rather than the last
    alphanumeric one).
