LOCAL_OPTIONS also preserves PRIVILEGED and RESTRICTED (which does not 
seem to be documented btw). Initially I made this optional but changed 
on your request :)

Oh, it was just saving extra unsetopt and localizing code :)

OK; as I already said, adding extra option to emulate is really the 
minor problem.
