Remove the 'not in' operator (!!=).  This was a hangover from Berkeley
days that was obsolete the moment we had IN (SELECT ...) capability.
It's arguably a security hole since it applied no permissions check to
the table it searched, and since it was never documented anywhere,
removing it seems more appropriate than fixing it.
