Misconsistency in installation files causes wrong warning regarding file modifications

Update package: phpBB-3.0.7-PL1_to_3.0.8.zip
File: old\index.php
Content:
{{<?php
/**
*

• @package phpBB3
• @version $Id$
• @copyright (c) 2005 phpBB Group
• @license http://opensource.org/licenses/gpl-license.php GNU Public License
  *
  */}}

Content of real file of phpBB-3.0.7-PL1 installation:
{{/**
*

• @package phpBB3
• @version $Id: index.php 9614 2009-06-18 11:04:54Z nickvergessen $
