That is what I thought
(defun my-copy-to-buffer (buffer)
"Copy to specified BUFFER the whole buffer."
(interactive "BCopy to buffer: \n")
(let ((oldbuf (current-buffer)))
(with-current-buffer (get-buffer-create buffer)
(barf-if-buffer-read-only)
(erase-buffer)
(save-excursion
(insert-buffer-substring oldbuf (point-min) (point-max))))))
Does not work zero bytes where copied, there is something I miss, obviously.
