Description:
------------
We use your module for our forum. But since we disallow editing of post we want users to be notified if they forget closing tags etc.

Would it be possible to add a flag which disallows the auto correction and just throws a exception if the nesting etc is incorrect. It does not really matter if how this is done. Although it would be nice if it gives enough information see which tag is wrong (or at least which type of tag)

Reproduce code:
---------------
so given" [b]text[i]ddd[/b][/i] 

Expected result:
----------------
it would give some information saying your i tag is not closed yet.
