  Improve pretty printer for HsExpr
  
  Given a very deeply-nested application, it just kept printing
  deeper and deeper.  This small change makes it cut off.
  
  The main payload is
  
  * At the start of `pprExpr`
  * In the defn of `pprApp`
  
  A little bit of refactoring:
  
  * It turned out that we were setting the default cut-off depth to a
    fixed value in two places, so changing one didn't change the other.
    See defaultSDocDepth and defaultSDocCols
  
  * I refactored `pprDeeperList` a bit so I could understand it better.
  
  Because the depth calculation has changed, there are lots of small
  error message wibbles.
