Is there a way to clear whitespace on save, but
then "put it back" where the cursor is?
Here is one way:
(defadvice delete-trailing-whitespace
(around except-for-current-line activate)
"However, leave trailing whitespace before point alone."
(let ((save (when (looking-back "\\s-+" (line-beginning-position) t)
(match-string 0))))
ad-do-it
(when save (insert save))))
