        ( We drop our char, but also "a" from WORD: it won't
          have the opportunity to balance PSP because we're
          EXIT!ing. )

( pre-comment for tight LOAD: The 0x08==I check after INTERPRET
  is to check whether we're restoring to "_", the word above.
  if yes, then we're in a nested load. Also, the 1 in 0x06 is
  to avoid tons of "ok" displays. )
