If it MUST be broken sooner or later, better sooner. The newer RFC (http://www.faqs.org/rfcs/rfc2616.html, section 19.3 and others) specifies the older format (RFC 850 HTTP dates, which have 2-digit years) as acceptable input, but in practice years like 2008 are often not handled properly in the 2-digit format, and there's no need to use RFC 850 dates today. I am not aware of anything inside Emacs that cares about the url-get-normalized-date format. I think this is a very harmless bug fix that should go in the pretest as well. If anyone has a reason to stick with RFC 850 dates, please let me know. Ted
