Detailed Description

This is rarely used but needed for some flags, which are used for intern handling like INVISIBLE or WALK_OFF. Because some core functions like remove_ob() use this, it will be better we set this ONE time outside instead of every time in remove_ob(): we skip the call for the head in this way.
