*

*              wikilink. For instance, "NZR WB class" can be changed to
*              "NZR W<sup>B</sup> class", but [[C#]] is not an equivalent wikilink,
*              so [[C Sharp]] doesn't have its main title changed.
*
*              The function looks for a banner like this:
*              <div id="RealTitleBanner"> ... <span id="RealTitle">title</span> ... </div>
*              An element with id=DisableRealTitle disables the function.
