Stefan, it appears that your recent patch broke `diff-apply-hunk':

in a modified CVS file, I do C-x v = (vc-diff) and in the resulting
*vc-diff* buffer I do C-c C-a (diff-apply-hunk) to reverse the section
of the diff:

Debugger entered--Lisp error: (buffer-read-only #<buffer io.d.~1.204.~>)
  delete-region(223236 223574)
  (save-current-buffer (set-buffer buf) (goto-char (car pos)) (delete-region 
(car pos) (cdr pos)) (insert (car new)))
  (with-current-buffer buf (goto-char (car pos)) (delete-region (car pos) (cdr 
pos)) (insert (car new)))
  (cond ((null line-offset) (error "Can't find the text to patch")) ((and 
switched ...) (message "(Nothing done)")) (t (with-current-buffer buf ... ... 
...) (set-window-point ... ...) (diff-hunk-status-msg line-offset ... nil) 
(when diff-advance-after-apply-hunk ...)))
  (let* ((--rest--45507 ...) (buf ...) (line-offset ...) (pos ...) (old ...) 
(new ...) (switched ...)) (if --rest--45507 (signal ... ...)) (cond (... ...) 
(... ...) (t ... ... ... ...)))
  (progn (let* (... ... ... ... ... ... ...) (if --rest--45507 ...) (cond ... 
... ...)))
  (destructuring-bind (buf line-offset pos old new &optional switched) 
(diff-find-source-location (not reverse) reverse) (cond (... ...) (... ...) (t 
... ... ... ...)))
  diff-apply-hunk(nil)
* call-interactively(diff-apply-hunk)
