lisp/url/url-methods.el: Fix format error when http_proxy is empty string

Browse Source 
2006-09-18  Michael Olson  <mwolson@gnu.org>

	* url-methods.el (url-scheme-register-proxy): Handle case where
	getenv returns an empty string for http_proxy.  This prevents an
	error when calling `format' later on.
