Intention is to copy extracts from *w3m*-buffer with
`copy-rectangle-to-register'

However, calling `open-rectangle' I get an error,
because *w3m*-buffer is read-only. Toggling this it
works.

Question: Is this star, which causes the error in the
 interactive-form "*r\nP" of `open-rectangle' necessary? 

Thanks

How do you manage to call `open-rectangle' here?
`copy-rectangle-to-register' calls `extract-rectangle' which doesn't
modify the buffer.

Yes.  Because `open-rectangle' may modify the buffer.

Don't know wherefrom I got this idea.

Thanks. That's the right thing.

OK. See it.  Thanks again.

Lately the `register'-part of
`copy-rectangle-to-register' turned out not as suitable
for my needs. Tried to get rid of that.

What about such a thing?

(defun copy-rectangle (start end)
  " "
  (interactive "r")
  (let (extr)
    (dolist (elem (extract-rectangle start end))
      (setq extr (concat extr elem "\n")))
    (kill-new extr)))
