But then something like "http://host/cgi-bin/foo?&a=1&b=2" will be
broken.  It will be turned into "http://host/cgi-bin/foo&amp;a=1&amp;b=2".
That can't be right, since it not only re-injects an ampersand but
sticks an HTML character entity into an HTTP element..

How is a response header field like this

    Location: http://host/cgi-bin/foo&amp;a=1&amp;b=2

valid HTTP?
