Description:
------------
Calling stream_get_line may eat additional characters when reading a long line.  If the delimiter is not encountered, a number of additional characters are removed from the stream and are not returned with the next call to stream_get_line.  For some unknown reason, adding \r to the delimiter makes it work just fine.

Reproduce code:
---------------
<?PHP // 1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ

$fp = fopen('test.php', 'r'); // Open myself
DoTest($fp, 'ZZZ');  // Removes 3 characters
DoTest($fp, "\r");  // Doesn't break with \r for some reason

function DoTest($fp, $delim) {
	echo "Delim:  " . urlencode($delim) . "\n";
	rewind($fp);
	echo "   " . stream_get_line($fp, 10, $delim) . "\n";
	echo "   " . stream_get_line($fp, 10, $delim) . "\n";
}

Expected result:
----------------
Delim:  ZZZ
   <?PHP // 1
   234567890A
Delim:  %0D
   <?PHP // 1
   234567890A


Actual result:
--------------
Delim:  ZZZ
   <?PHP // 1
   567890ABCD
Delim:  %0D
   <?PHP // 1
   234567890A
