 This is a follow-up to #20434.

 WP_Http still fails (A valid URL was not provided.) with some urls with
 relative url redirects.

 I was scraping web.archive.org with a plugin.

 The combination of the relative redirects plus this kind of url:


 {{{
 http://web.archive.org/web/20131001160642/http://www.spiegel.de/thema/deutschland_nach_der_bundestagswahl/
 }}}

 is the culprit.

 I think the problem is the check on the scheme in ::make_absolute_url
 where it does:


 {{{
         // Check for a scheme
         if ( false !== strpos( $maybe_relative_path, '://' ) )
                 return $maybe_relative_path;
 }}}

 so that a relative url like
 /web/20131001160642/http://www.spiegel.de/thema/deutschland_nach_der_bundestagswahl/
 it's evaluated as absolute.
