Description:
------------
The documentation of FilesystemIterator::__construct() (http://de.php.net/manual/en/filesystemiterator.construct.php) suggests that it is possible to use arbitrary valid flags for the iterator.

I do not fully understand the PHP source, but…

/* {{{ proto void FilesystemIterator::__construct(string path [, int flags])
 Cronstructs a new dir iterator from a path. */
SPL_METHOD(FilesystemIterator, __construct)
{
        spl_filesystem_object_construct(INTERNAL_FUNCTION_PARAM_PASSTHRU, DIT_CTOR_FLAGS | SPL_FILE_DIR_SKIPDOTS);
}
/* }}} */

The code above makes me believe that the flag SPL_FILE_DIR_SKIPDOTS is *always* added to the flags when using the FilesystemIterator. So it is not possible to make the flag NOT be there, by for example using 0 as argument.

So either this is a documentation issue, or this is an implementation bug.

Test script:
---------------
<?php
$oDirectoryIt = new FilesystemIterator('.', 0);
$oDirectoryIt->setFlags(0);

foreach ($oDirectoryIt as $oDirectory) {
        var_dump($oDirectory);
}
?>

Expected result:
----------------
I expect to see "." and ".." in the output.

Actual result:
--------------
I do not see "." or "..".
