    Special case the bracket matching tag when printing
    
    Back when we created the compositor, we didn't treat bracket match tags
    in a special way, because we wanted a more generic way to mark certain
    tags for printing or not. But given that we didn't add that api and that
    in all this time bracket match was the only problem reported, go for the
    special case solution.
