[Patch] url-http-create-request creates truncated paths

[Diane Murray <disumu@x3y2z1.net>]

Argument and value pairs separated by semicolons in URLs, parsed as
attributes in URL/Emacs, are being left out of HTTP requests.  This
results in 404 errors or the wrong page being retrieved.  For example,
the request for the URL
<http://www.emacswiki.org/cgi-bin/wiki?action=browse;oldid=Gnus;id=GnusPage>
is "GET /cgi-bin/wiki/?action=browse HTTP/1.1" - note that everything
following the first semicolon is ignored in the request.

Additionally, I believe - in http:// URLs, at least - the target (like
#top) belongs at the very end of the URL, yet `url-recreate-url'
places it just before any attributes.  Please see the following patch
for fixes.


	* url-parse.el (url-recreate-url-attributes): New function, code
	simply moved from `url-recreate-url'.
	(url-recreate-url): Use it.  Put the `url-target' at the end of
	the URL after the attributes.

	* url-http.el (url-http-create-request): Use
	`url-recreate-url-attributes' when setting real-fname.
