  It stands for "non-consing".  You will also find it in nconc, nreconc,
  nreverse, nbutlast, nsubst[-if[-not]], nsublis, nsubstitute[-if[-not]],
  nintersection, nset-difference, and nset-exclusive-or which are non-
  consing versions of the function named without the n prefix, except for
  nconc which is the non-consing version of append.

  The past is not more important than the future, despite what your culture
  has taught you.  Your future observations, conclusions, and beliefs are
  more important to you than those in your past ever will be.  The world is
  changing so fast the balance between the past and the future has shifted.
