Description:
------------
fstat() returns result array with both associative & numerics indexes, but documentation says only about associative ones.

Reproduce code:
---------------
<?php
$fp = fopen(__FILE__,'r');
var_dump(fstat($fp));
?>

Expected result:
----------------
Array
(
    [dev] => 771
    [ino] => 488704
    [mode] => 33188
    [nlink] => 1
    [uid] => 0
    [gid] => 0
    [rdev] => 0
    [size] => 1114
    [atime] => 1061067181
    [mtime] => 1056136526
    [ctime] => 1056136526
    [blksize] => 4096
    [blocks] => 8
)

Actual result:
--------------
array(26) {
  [0]=>
  int(773)
  [1]=>
  int(115763)
  [2]=>
  int(33188)
