Description:
------------
phpdbg should have the same capabilities as the php cli, however the display_errors=stderr ini setting does not work.

Test script:
---------------
--fatal.php--
<?php
class FatalTest {}
eval('class FatalTest {}');

$ phpdbg -ddisplay_errors=stderr -qrr fatal.php 2>/dev/null
$ php -ddisplay_errors=stderr fatal.php 2>/dev/null

Expected result:
----------------
Nothing output to the terminal

Actual result:
--------------
Fatal error and stack trace are shown after the phpdbg command on the terminal stdout.
