Description:
------------
When using the CURLINFO_HEADER_OUT option HTTP version option seem to be bypassed (1.1 is forced)

Test script:
---------------
// ...

curl_setopt($curlSession, CURLINFO_HEADER_OUT, true);

// Mark as HTTP request
curl_setopt($curlSession, CURL_HTTP_VERSION_1_0, true);

// ...

// Send the request
$response = curl_exec($curlSession);
$request  = curl_getinfo($curlSession, CURLINFO_HEADER_OUT);

echo $request

Expected result:
----------------
// kind of
