Ah okie.  True.  Will fix.

COMPILE-ONLY is separate from IMMEDIATE; there's also (at least one)
COMPILE-ONLY word that isn't IMMEDIATE.  COMPILE-ONLY just means that
the interpreter will complain if you try to use the word while STATE
is OFF .

I think we'll be able to cope without an FCODE-IMMEDIATE flag as well; I
think all FCode's with special compilation semantics are separate from
normal Forth words anyway, so IMMEDIATE will do fine.

Anyway, I might give in and put the FCode in the words' headers.  We'll see...
