Oh, now I understand what you want. Actually here you faced with
another problem: when you enable whitespace-mode in emacs 24.3.1,
"whitespace-line" becomes the only active face in a long line, and in
emacs 24.4 it is added to the faces in that line.
So let's say, you have the following long line in a buffer with
"emacs-lisp-mode" (and "whitespace-mode" is enabled):
(defun some-function (arg1 arg2 &rest args) "A very useful function." (interactive) (message "Hello"))
If you move your cursor to the "defun" word and press "C-4 C-x =", in
the bottom of the "*Help*" buffer you will see:
There are text properties here:
face whitespace-line
fontified t
I.e. only "whitespace-line" face is active and you can't see
"font-lock-keyword-face" (used for highlighting "defun") no matter how
you customized "whitespace-line".
As for emacs 24.4, you will see:
There are text properties here:
face (whitespace-line font-lock-keyword-face)
fontified t
In this case if some bits of face spec are unspecified in
"whitespace-line" face, the ones from "font-lock-keyword-face" are used.
So that is not the same problem we were discussing before, but it is
also fixed in emacs 24.4.
