  When this happens in the read-eval-print-loop (or listener) that you are
  using, one easy way to get the whole result is to type this immediately
  after you have received the answer:

(pprint *)

  I think it is a feature of the listener to abbreviate returned values.

  Please note that this has very little or nothing to do with *print-level*
  or *print-length*.  Those variables control the output of your own calls
  to print (or pprint).  The print of the listener should not use them, but
  should have its own set of such printer control variables.
