Description:
------------
The documentation for array_slice currently states that "Note: This function will 
reset() the array pointer of the input array after use.", which is not true. After 
having reviewed the source and confirmed with a test I'm submitting a patch to 
remove this note from the docs.

Below I've provided a test script to prove that this behavior is non-existent.

I also have a patch from edit.php.net to remove this note. Thanks.

Test script:
---------------
<?php
$array = array(1,2,3,4);

/* This should produce int(2) */
var_dump(next($array));

$slice = array_slice($array, -1);

/* This should still produce int(2) */
var_dump(current($array));

$slice = array_slice($array, 2, 1);

/* This should still produce int(2) */
var_dump(current($array));

/* This proves the array's internal pointer was never changed by array_slice() */


Expected result:
----------------
int(2) int(1) int(1)

Actual result:
--------------
int(2) int(2) int(2)
