note 13430 added to pear.standards.php

I think it would be a good idea, to name the files in this way: eg. Classname DB_Msyql so the filename should have the name DB_Mysql.class.php This would be easier to find the source of the documented Class and easier for phpdoc to find the fild to be documented. Another benefit is, that its obvious that its a php-class file and not other code http://www.php.net/manual/en/pear.standards.php
