Description:
------------
Command Line curl output with linefeeds. Displayed correctly in terminal.
curl -vvv 'localhost:9200/_cat/nodes/?v'
* Hostname was NOT found in DNS cache
*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 9200 (#0)

host                                      ip             heap.percent ram.percent load node.role master name
es-thr-hdp-02.dbplat.altus.bblabs.rim.net 10.236.133.15            3          55 0.01 d         m      es-thr-hdp-02
es-thr-hdp-01.dbplat.altus.bblabs.rim.net 10.236.133.17            9          56 0.00 d         *      es-thr-hdp-01

Same output in php displayed out put in browser without linefeed as a single line:

HTTP/1.1 200 OK Content-Type: text/plain; charset=UTF-8 Content-Length: 357 host ip heap.percent ram.percent load node.role master name es-thr-hdp-02.dbplat.altus.bblabs.rim.net 10.236.133.15 3 55 0.00 d m es-thr-hdp-02 es-thr-hdp-01.dbplat.altus.bblabs.rim.net 10.236.133.17 9 56 0.00 d * es-thr-hdp-01 


Test script:
---------------
function get_web_page( $url )
{
    $options = array(
        CURLOPT_RETURNTRANSFER => true,     // return web page
        CURLOPT_HEADER         => true,    // don't return headers
        CURLOPT_VERBOSE        => true,    //
        CURLOPT_CRLF           => true,    //
        CURLOPT_FOLLOWLOCATION => true,     // follow redirects
        CURLOPT_ENCODING       => "",       // handle all encodings
        CURLOPT_USERAGENT      => "spider", // who am i
        CURLOPT_AUTOREFERER    => true,     // set referer on redirect
        CURLOPT_CONNECTTIMEOUT => 5,      // timeout on connect
        CURLOPT_TIMEOUT        => 5,      // timeout on response
        CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
        CURLOPT_HTTPHEADER      => array('Content-Type: text/plain'),       //
    );
....
   $url = "http://$master_nodes:9200/_cat/nodes?v";
   echo "<br>";
   $curl_response = get_web_page( $url );
   echo $curl_response['content'];
   echo "<br>";




Expected result:
----------------
Output should be on different lines: as below


HTTP/1.1 200 OK 
Content-Type: text/plain; charset=UTF-8 
Content-Length: 357

host ip heap.percent ram.percent load node.role master name 
es-thr-hdp-02.dbplat.altus.bblabs.rim.net 10.236.133.158 3 55 0.00 d m es-thr-hdp-02 
es-thr-hdp-01.dbplat.altus.bblabs.rim.net 10.236.133.157 9 56 0.00 d * es-thr-hdp-01 

Actual result:
--------------
HTTP/1.1 200 OK Content-Type: text/plain; charset=UTF-8 Content-Length: 357 host ip heap.percent ram.percent load node.role master name es-thr-hdp-02.dbplat.altus.bblabs.rim.net 10.236.133.158 3 55 0.00 d m es-thr-hdp-02 es-thr-hdp-01.dbplat.altus.bblabs.rim.net 10.236.133.157 9 56 0.00 d * es-thr-hdp-01 

Note: Content Array returned has only 1 element for single line.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Specifically, what's the rest of get_web_page's code?
