- Martin Drasar provided the CURLOPT_POSTREDIR patch. It renames

CURLOPT_POST301 (but adds a define for backwards compatibility for you who
  don't define CURL_NO_OLDIES). This option allows you to now also change the
  libcurl behavior for a HTTP response 302 after a POST to not use GET in the
  subsequent request (when CURLOPT_FOLLOWLOCATION is enabled). I edited the
  patch somewhat before commit. The curl tool got a matching --post302
  option. Test case 1076 was added to verify this.
