Actually I just use Vim with trailing whitespace highlighting turned on 
(http://www.vim.org/scripts/script.php?script_id=790) and remove 
trailing whitespace by myself when appropriate or annoying. I think it's 
important (well at some point) for make code cleaner. Also trailing 
whitespace may prevent some Vi commands like '{' and '}' to work as 
expected. And there is even a note about trailing whitespace at the end 
of PEP-8.
