It's easy enough to implement with something like this, though:

| (dolist (elt (mapcar (function buffer-name) (buffer-list)) nil)
|   (save-current-buffer
|     (set-buffer elt)
|     (if (not buffer-read-only)
|       (progn ...))))

A friend of mine used the following to reindent many XML/HTML files and
was kind enough to share it:

| (defun indent-all-buffers ()
|   "Reindent all currently open buffers, as long as they are
| not read-only.  Read-only buffers are simply skipped."
|   (interactive)
|   (dolist (elt (mapcar (function buffer-name) (buffer-list)) nil)
|     (save-current-buffer
|       (set-buffer elt)
|       (if (not buffer-read-only)
|           (indent-region (point-min) (point-max) nil))))
