[Gazpacho] Emacs and trailing whitespace

[Johan Dahlin]

Hi fellow hackers

I just committed a quite big patch to remove trailing whitespace in all 
python files.
It's kinda annoying, since they tend to show up in patches.

In emacs, if you add this to your .emacs you'll see a big red block in 
all places where there
are trailing whitespaces:

(mapc (lambda (hook)
      (add-hook hook (lambda ()
		  (setq show-trailing-whitespace t))))
      '(python-mode-hook))

To remove all whitespace in a buffer, just type M-x delete-trailing-whitespace

Could all emacs users please add this so we can keep them from creeping in again?

Cheers

Johan
