Description:
------------
The FILTER_VALIDATE_EMAIL check fails with valid adresses that contain "--" twice because they have e.g. a German Umlaut ("ä") after a dash ("-").

The following examples can be verified using the converter tool on the DeNIC page at http://www.denic.de/domains/internationalized-domain-names/idn-konvertierung.html

 IDN: example-ä.de
 ACE-String: xn--example--7za.de


Test script:
---------------
--TEST--
Bug #XXXXX (FILTER_VALIDATE_EMAIL fails with valid addresses containing "--" twice)
--FILE--
<?php

$email_address = "test@xn--example--7za.de"; // "example-ä.de"
var_dump(filter_var($email_address, FILTER_VALIDATE_EMAIL));    

?>
--EXPECTF--
%unicode|string%(21) "test@xn--example--7za.de"


Expected result:
----------------
"test@xn--example--7za.de"

Actual result:
--------------
bool(false)
