JSLint (www.JSLint.com) was updated recently to include new RegExp
literal policies. http://www.JSON.org/json.js and
http://www.JSON.org/json2.js have been updated to pass the updated JSLint.
It is strongly recommended that you be using an edition of json.js
that is no earlier than 2008-03-14.
If you have developed your own JSON for JavaScript package that uses
the json.js RegExp literals, then you should update your package as well.
