Log Message:
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.
