Description:
------------
It seems that stream_get_contents() isn't respecting the second paramether, limit.
I think this only happen for http wrappers.

Reproduce code:
---------------
<?
$fp = fopen('http://www.php.net/', 'r');

echo strlen(stream_get_contents($fp, 50));

fclose($fp);

?>

Expected result:
----------------
50

Actual result:
--------------
