Description:
------------
Documentation says that Locale::filterMatches has two parameters, but reflection shows three:

Method [ <internal:intl> static public method filterMatches ] {

  - Parameters [3] {
    Parameter #0 [ <required> $arg1 ]
    Parameter #1 [ <required> $arg2 ]
    Parameter #2 [ <required> $arg3 ]
  }
}

And in OO example is used incorrect method name Locale::filter_matches instead of Locale::filterMatches.

http://docs.php.net/manual/en/locale.filtermatches.php

Reproduce code:
---------------
var_dump(Locale::filterMatches('de-DE-1996', 'de-DE'));

Expected result:
----------------
bool(%b)

Actual result:
--------------
Warning: Locale::filterMatches() expects exactly 3 parameters, 2 given in %s on line %n
bool(false)
