Fixed. Seems so. I hope.

I corrected high-level definitions for CREATE :NONAME (and eventually for
the high-level definitions of : colon and ; semis).  I implemented (CREATE)
based on my incorrect definition for :NONAME and parts from other related
defs, and older versions in my backups.  I found one bug too ...  :NONAME's
no longer have a dictionary header.  Other words are correctly linked
around :NONAME's dictionary space, don't overwrite it's space, etc.

I implemented LATESTXT.  LATESTXT is updated with LAST everywhere LAST
is stored, and also set to HERE in :NONAME.  I changed RECURSE to use
LATESTXT instead of LAST and updated RECURSE to compile R> DROP to not
overflow the return stack. This was caused from numerous ENTER (or DOCOL)
 from recursing without an EXIT (or SEMIS). I had that previously but backed
it out at some point for reasons unknown now.

I had hoped to not use LATESTXT by just temporarily updating LAST ,
but the value it needed to be preserved for too long.  It would've had to
have stayed set until ; semis and then reset to it's prior value.  That
appeared to lead to a coding mess.  I.e., how do you know when to reset
or leave it alone? ...  I think Mark Wills was running into this.

I did run into an issue with DOVAR.  Actually, it affects DOVAR DODOES
and ENTER (or DOCOL) or any other CFA field address.  I can set them up
as routines ((non-existant i.e., just returns address) or as constants.
E.g., I can make DOVAR work for either of these def's, but not both:

: CREATE (CREATE) COMPILE DOVAR ;  \ DOVAR address as a routine

: CREATE (CREATE) DOVAR , ;  \ DOVAR address as a constant

When setup as a constant, they don't crash my system when entered
interactively.  I *cannot* install a fake do-nothing routine for them when
setup as a routine, i.e., they will crash if used interactively.  They're
only used when compiled or comma'd into a definition's CFA.  Or, at least,  
I
can't think of a non-CFA use for them ...  So, I went with constants for  
now.
