2, definitely.  Otherwise you could screw up royally by typing, for instance:

	: FOO   [ ASSEMBLER ]  SWAP  ;

In F83, there is a separate variable LAST that remembers the most recent
word.  This is necessary because F83 implements "smudging" by unlinking
the word from the vocabulary thread while it is being defined, and hooking
it back in when the definition is complete.

Actually, my personal belief is that there should not be a separate
CURRENT vocabulary.  Definitions should go into the first vocabulary
in the search order.  But we've already had that discussion...
