Annoyed by trailing whitespace? In Vim, to find it: /\s\+$, then cycle thru matches with n and delete, if appropriate, with D. Yes, :set hlsearch may help. Alternatively, if you are totally sure that no trailing whitespace is ever wanted in your code: :%s/\s\+$//. Finally, if you want to visually indicate trailing whitespace using Vim's syntax highlighting:
:syn match TRAILING_WS "\s\+$"
:hi link TRAILING_WS Error
