The bug report holding all is the first one
http://bugs.typo3.org/view.php?id=8978

There are no news, but this patch fixes some reg exp errors so the 
reported errors are gone.

Also it improves execution time a lot.

I can't deliver a perfect solution, so i prefer smaller steps by 
committing this version, as it solves the problem with substituting 
normal content.
So users can start to use the class, the actual script isn't usable.

I also provided a script for testing all "possible" hacks for testing.
