// @name           Google Search link cleaner
// @namespace      tgr
// @description    A simple script to clean urls of the result links on the Google Search page
//                 An onmousedown event handler changes those urls to point to www.google.*/url?... to count clicks
//                 which can be extremely annoying because it messes up right-click "copy link location" functionality
//                 This script installs a second event handler which instantly restores the original url
// @include        http://www.google.co*/search?*
// ==/UserScript==

// return a query parameter from an url; null if not found
function getParameter(url, name) {
    var paramsStart = url.indexOf("?");
    if(paramsStart == -1) return null;
    var paramsEnd = url.indexOf("#");

        queryString = url.substr(paramsStart + 1);
    else

    var parameters = queryString.split('&');

        var values = parameters[i].split('=');
        if(values[0] == name)
            return unescape(values[1]);
    }
    return null;
}

// if the url begins with "/url", get the original url (which is now in the "url" parameter of the query string)
// then remove our event listener (the original event handler runs only once so there's no further need)
