delete-trailing-whitespace deletes whitespace at LEFT but not at
BOTTOM!? How do BOTTOM too?
In other words... if I have a bunch of newlines at the end, e.g.
\n\n\n\n\n
...How replace them with just one \n?

In addition,
(setq next-line-add-newlines nil)
helps to prevent inserting empty lines at the end of files.

Don't you have to add (delete-trailing-whitespace) to
your write-file-hook??
I made a version based on yours that is almost perfect...
(defun cs-delete-trailing-whitespace() (interactive)
(delete-trailing-whitespace)
(let ((original-pos (point)))
(goto-char (point-max))
(delete-blank-lines)
(goto-char original-pos)))
and
(add-hook 'write-file-hooks 'cs-delete-trailing-whitespace)
For some reason these additions make me unable to do save-buffer!!!
I can't do M-x save-buffer anymore!!
M-x save-buffers-kill-emacs still works for some reason.
