  * Add history/trace functionality to the GHCi debugger
  
  The debugger can now log each step of the evaluation without actually
  stopping, keeping a history of the recent steps (currently 50).  When
  a (real) breakpoint is hit, you can examine previous steps in the
  history (and their free variables) using the :history, :back and
  :forward commands.
