      In general, you should always acquire security settings unless
      you have a specific reason not too. This will make managing your
      security settings much easier as much of the work can be done
      from the root folder.

         So, does "Acquire permission settings" override all permissions specifically set in a folder's security or
         does it append the specifically set permission to the acquired permissions?

         Like
         permitted(here, perm, role)
         = (here.checked(perm, role)
            OR (    here.checked(perm, "Acquire...") 
                AND permitted(here.aq_parent, perm, role)) 

         where OR, AND is conditional OR, AND resp.???
