URL not following some 302 redirects after recent changes

[Diane Murray]

Sometime after 2006-10-26 URL redirects stopped working correctly
(Emacs CVS of 2006-09-19 and 2006-10-26 works, 2006-10-31 and
2006-11-19 don't work), perhaps due to changes made in revision 1.36
of url-http.el.

For example, <http://www.cliki.net/cliki> returns the following
headers, but `url-retrieve' runs the callback function instead of
first retrieving the new location:

HTTP/1.0 302 Redirected

The above-mentioned working versions retrieve the redirected URL
correctly.
