Incompatibility of CC mode

[Richard Stallman]

Is there any good reason for this incompatibility?
If not, let's get rid of it.

Subject: c-subword-mode - inconsistent behavior

The functions c-capitalize-subword, c-downcase-subword, c-upcase-subword
claim to behave like their normal emacs counterparts, but all three
functions move the point when given a negative argument.  Furthermore,
c-capitalize-subword doesn't even work with a negative argument on my
machine.  I changed the functions to better mimic the behavior of
capitalize/downcase/upcase/-word: they no longer move point with a  
negative
argument.

Here's my code:

(defun c-capitalize-subword (arg)
   "Do the same as `capitalize-word' but on subwords.
See the command `c-subword-mode' for a description of subwords.
Optional argument ARG is the same as for `capitalize-word'."
   (interactive "p")
   (let ((count (abs arg))
         (start (point)))
     (dotimes (i count)
       (when (if (< arg 0)
                 (re-search-backward
                  (concat "\\<[" c-alpha "]")
                  nil t)
               (re-search-forward
                (concat "[" c-alpha "]")
                nil t))
        (goto-char (match-beginning 0)))
       (let* ((p (point))
              (pp (1+ p))
             (np (c-forward-subword)))
        (upcase-region p pp)
        (downcase-region pp np)
        (if (< arg 0)
             (c-backward-subword)
           (goto-char np))))
     (if (< arg 0) (goto-char start))))

(defun c-downcase-subword (arg)
   "Do the same as `downcase-word' but on subwords.
See the command `c-subword-mode' for a description of subwords.
Optional argument ARG is the same as for `downcase-word'."
   (interactive "p")
   (let ((start (point)))
     (downcase-region (point) (c-forward-subword arg))
     (if (< arg 0) (goto-char start))))

(defun c-upcase-subword (arg)
   "Do the same as `upcase-word' but on subwords.
See the command `c-subword-mode' for a description of subwords.
Optional argument ARG is the same as for `upcase-word'."
   (interactive "p")
   (let ((start (point)))
     (upcase-region (point) (c-forward-subword arg))
     (if (< arg 0) (goto-char start))))
