I think I may have found the ultimate emacs solution.  It really
annoys me to see the trailing whitespace in my buffer.  When I start a
new indented line but end up not adding anything there, it highlights
the region from the left of the to where the cursor was a trailing
whitespace so I have a lot of ugly red blocks in my buffer.  My new
solution is not to highlight it, but to add a hook to emacs to delete
it whenever I save my buffer.

(add-hook 'python-mode-hook
          (lambda ()
	    (add-hook 'local-write-file-hooks 'delete-trailing-whitespace)
	    ))

Now I can be blissfully unaware of trailing whitespace as before, and
my editor will clean it out on save.
