url-gw.el: Cannot use proxy with url-gw.el 1.15

[Shun-ichi GOTO]

Url package in cvs head cannot use http proxy.
# gateway method is default (native).

For example, this simple code fail with url-gw.el rev 1.15
 (url-retrieve "http://www.gnu.org/"; 'ignore))
but success with url-gw.el rev 1.14.

With rev 1.15, url-retrieve<f> issue GET requests
  GET http://zippo:8080/...       (incorrect!)
against proxy server instead of
  GET http://www.gnu.org/...      (correct)

 (Note: zippo:8080 is proxy in my local net)

I don't know why changes between two revs cause so.
