    src/hattools         HatStack.hs HatTrail.hs SExp.hs VSExp.hs 
  Log:
  Tidy up SExp code, in particular to put back necessary parentheses in
  pretty-printed expressions.  Also, do not store the result of an
  if/case/guard unless needed (by hat-anim), since storing it
  unnecessarily leads to unbounded resource usage in the other tools.
