Description:
------------
The LimitIterator doesn't seem to follow the Iterator contract: It's not possible to iterate using the Iterator methods.

Reproduce code:
---------------
$limitIterator = new LimitIterator(new ArrayIterator(array('foo')));

$arrayIterator = new ArrayIterator(array('foo'));

$limitItValue = $limitIterator->current();
$arrayItValue = $arrayIterator->current();

Expected result:
----------------
$limitItValue and $arrayItValue to be equal (both 'foo')

Actual result:
--------------
$limitItValue ends up being NULL, while $arrayItValue has the expected value 'foo'.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

You have to call rewind() before accessing current(), without calling rewind() the current value is undefined.
