// @name Obviously Scrub Google Redirect Links
// @description Removes the Google redirect in search result links, and adds an extra plain link so you can be sure it's done it. Built on ping's scrub script
// @include http://www.google.com/search?*
// @include http://www.google.co.uk/*
// ==/UserScript==
// 20101108 use encodeURIComponent so + in queries works properly
// 20101115 Non-redirecting pager links now working
// 20101118 New pager links now more robust
// 20101123 Use 'location hack' to delete Google's variables. Also remove useless attempts to remove event listeners
// 20101207 Bug fix: URLs for pager links got progressively more mangled if they had escapes in. Fixed. Also make pager links bigger and centred.
// Please note, this is a development, pre-alpha version of the script
// which still generates trace output and is subject to constant change
