Description:
------------
the !i is used in the root tag so [i] cannot be a child of the root tag and will not be replaced.

so the exemple should output [i]Italic Text[/i] and not <i>Italic Text</i>


Reproduce code:
---------------
---
From manual page: function.bbcode-create
---
exec the exemple 

Expected result:
----------------
<b>Bold Text</b>
[i]Italic Text[/i]
