    # 2011-03-13 (ADH): The ROOL Wiki only supports [[these]] links as allowing
    #                   CamelCase would fall foul of numerous non-link cases in
    #                   its technical content. Accordingly, when the Wiki shows
    #                   titles for missing pages and so forth, we *don't* want
    #                   it to mungle the title. Really, Instiki probably ought
    #                   to disable this according to the relevant Web setting
    #                   but it doesn't pass that information down to here.
