Amen.  The solution I posted was something I gave to a friend and
coworker around five years ago, on a system where there was no
Icon or Perl or tac.  Such systems still exist.  There's always
more than one way to solve a problem.  And since not everyone has
access to the same tools, this is fortunate.
