I'm not claiming it is totally wrong. As I said I did not look at what
it does. All I want to ask for: If you reinvent the wheel please make
it at least round. Better learn from the wheels that were there before.
It's really depressing to see the same security problems again and
again and again.

All I ask for is that you understand that you are about the change the
relavant semantics of something security relevant, and act accordingly.

Some filemanagers might have security problems. Being able to hide
a security problem by another security problem does not reduce the
