Details:

The definition

: foo { a1 a2 a3 a4 a5 a6 a7 a8 a9 a10 } 
      { b1 b2 b3 b4 b5  b6 b7 b8 b9 b10  } 
      { c1 c2 c3 c4 c5  c6 c7 c8 c9 c10  } ;


produces the error message 

"[filename].fs:3: Dictionary overflow
      { c1 c2 >>>c3<<< c4 c5  c6 c7 c8 c9 c10  } ;"

and then leaves the interpreter in a wedged state where hasn't seen the
closing brace but doesn't let you add one.

Yes I really did want to write a definition with that many locals ;-).

It would be nice if the limit could be eliminated or increased by a lot, and
also if the interpreter recovered properly when the error is triggered.
