// "Technical restrictions" title fix

// For pages that have something like Template:Lowercase, replace the title, but only if it is cut-and-pasteable as a valid wikilink.

//============================================================

// (for instance [[iPod]]'s title is updated. <nowiki>But [[C#]] is not an equivalent wikilink, so [[C Sharp]] doesn't have its main title changed)</nowiki>

//******** written by User:Interiot ********

// For pages that have something like Template:Lowercase, replace the title, but only if it is cut-and-pasteable as a valid wikilink.

// The function looks for a banner like this: <nowiki>

// (for instance [[iPod]]'s title is updated. But [[C#]] is not an equivalent wikilink, so [[C Sharp]] doesn't have its main title changed)

// <div id="RealTitleBanner"> <!-- div that gets hidden -->

//

// <span id="RealTitle">title</span>

// The function looks for a banner like this:

// </div>

// <div id="RealTitleBanner"> <!-- div that gets hidden -->

// </nowiki>An element with id=DisableRealTitle disables the function.

// <span id="RealTitle">title</span>
