[cvs-nhc98] patch applied (hat): Turn list sugaring back on by default, but ensure that no ambiguous

Tue Jun 18 07:55:58 PDT 2002 malcolm * Turn list sugaring back on by default, but ensure that no ambiguous list sugaring is generated, by testing whether the ultimate tail of a list is Hidden, Unevaluated, or Interrupted. A cutoff tail is represented with an additional `...' to remind the user that there are more elements of the list.
