[Haskell-cafe] emacs haskellers: r-stripping files becomes popular

[Greg Heartsfield]

Additionally, I find this to be helpful for keeping out trailing
whitespace:

;; Highlight trailing whitespace in haskell files
(add-hook 'haskell-mode-hook
          '(lambda ()
             (setq show-trailing-whitespace t)))

Cheers,
