  * When pretty-printing string expressions, avoid the appearance of [...]
  due to cutoff depth, for instance in the following:
      ["one","tw...","t...",[...],...]
  The solution is to peek one character ahead of the cutoff depth in order
  to decide between string/list sugaring.  The example above becomes:
      ["one","two","th..","f...",...]
  given the same cutoff depth.
