Hot tip for vim users: highlight spaces at end of lines

[Chris Sherlock]

Probably best to use:

augroup trailing_whitespace
   autocmd!
   autocmd BufWritePre *.c :%s/\s\+$//e
   autocmd BufWritePre *.h :%s/\s\+$//e
   autocmd BufWritePre *.cxx :%s/\s\+$//e
   autocmd BufWritePre *.hxx :%s/\s\+$//e
augroup END
