Attached patch fixes a typo and also removes trailing white spaces.

The white spaces were removed due to adding a hook to remove them as
shown here:

	(defun kimr-before-save-hook ()
	  "Delete trailing white spaces only in a few modes."
	  (when (eq major-mode 'org-mode)
	    (delete-trailing-whitespace)))

	(add-hook 'before-save-hook 'kimr-before-save-hook)

Please let me know if trailing white spaces should not be removed in
general so that I will omit such changes in future patches.
Thanks.
