/**
 * InstaView - a Mediawiki to HTML converter in JavaScript
 * Version 0.6.1
 * Copyright (C) Pedro Fayolle 2005-2006
 * http://en.wikipedia.org/wiki/User:Pilaf
 * Distributed under the BSD license
 *
 * Changelog:
 *
 * 0.6.1
 * - Fixed problem caused by \r characters
 * - Improved inline formatting parser
 *
 * 0.6
 * - Changed name to InstaView
 * - Some major code reorganizations and factored out some common functions
 * - Handled conversion of relative links (i.e. [[/foo]])
 * - Fixed misrendering of adjacent definition list items
 * - Fixed bug in table headings handling
 * - Changed date format in signatures to reflect Mediawiki's
 * - Fixed handling of [[:Image:...]]
 * - Updated MD5 function (hopefully it will work with UTF-8)
 * - Fixed bug in handling of links inside images
 *
 * To do:
 * - Better support for <math>
 * - Full support for <nowiki>
 * - Parser-based (as opposed to RegExp-based) inline wikicode handling (make it one-pass and bullet-proof)
 * - Support for templates (through AJAX)
 * - Support for coloured links (AJAX)

// IE madness with encoding
// ========================
//
// suppose throughout that the page is in utf8, like wikipedia
//
// if a is an anchor DOM element and a.href should consist of
//
// http://host.name.here/wiki/foo?bar=baz
//
// then IE gives foo as "latin1-encoded" utf8; we have foo = decode_utf8(decodeURI(foo_ie))
// but IE gives bar=baz correctly as plain utf8
//
// ---------------------------------
//
// IE's xmlhttp doesn't understand utf8 urls. Have to use encodeURI here.
