Description:
------------
escapeshellarg() returns null when passed an empty string instead of returning an empty string.  The documentation doesn't say anything about giving a return value of null.

Reproduce code:
---------------
<?php
var_dump(escapeshellarg(''));
?>

Expected result:
----------------
string ''

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

5_2 returns NULL (wrong value) , for some reason 5_3 is right.
