    ircParser: Trim trailing whitespace from commands
    
    The command tab-completion added in commit 68758eaf1 appends a space
    after the inserted command, which makes sense for commands that take
    parameters, but currently breaks those that don't - it is rather silly
    to treat "/help " as anything other than "/help" though, so simply
    strip trailing whitespace.
