    Be robust against munged comments
    
    Bugzilla 3.4 currently has bug where it line-wraps (and strips trailing
    whitespace) from comments in the XML output.
    
    Try to robust against this by ignoring lines we don't know about and
    treating '' the same as ' '. If the wrong thing gets wrapped, we can
    get confused and get a blank comment, but it's better than having
    the page stop loading entirely.
