/** * Fix the MediaWiki diffs (including AJAX ones). * Display the diffs in monospace font with white-space preservation. * We can't just use CSS for this because MediaWiki generates bad diffs; there are * unnecessary new-lines added at the start and end of each modified line in the * diff which obviously end up being shown unless we fix it. * This script strips the unnecessary new-line characters as well as setting * the inline styles to monospace/pre-wrap (Easier to manage all in one place). * * The Edit page fixing only works in browsers with MutationObserver support. * Those are Firefox14+ or Chrome18+. * NOTE: Wikia uses $.showModal to show the edit popups, I can assume that and *  install a hook instead of using the body observer but that doesn't really *  help with the table insertion. I think jQuery's append provides a hook which *  would allow me to replace the popup observer but it's more foolproof just to *   use the browser feature instead. */ jQuery(function($) {	"use strict";	var w = window,	   document = w.document,	    console = w.console || { error: $.noop },	    mw = w.mediaWiki || { config: { get: function(p) { return w[p]; } } };
