Description:
------------
The new php.net manual doesn't allow to add user notes unless at least one user note already exists. The "add a note" link is not shown if there are no existing user notes.

Test script:
---------------
Note exists, link is shown: http://at1.php.net/manual/en/class.exception.php
No note, no link: http://at1.php.net/manual/en/exception.tostring.php


Expected result:
----------------
Expected to see the "add a note" link if there are no notes yet!

Actual result:
--------------
"Add a note" link is not shown if there's no note yet
