It turned out that the CUA property of these cursor moving commands
caused the funny things I described above. I fixed it with this hook:

    (add-hook 'cua-mode-hook
              (lambda ()
                (dolist (cmd '(forward-char
                               backward-char
                               previous-line
                               next-line
                               forward-paragraph
                               backward-paragraph
                               beginning-of-buffer
                               end-of-buffer))
                  (put cmd 'CUA nil))))

I really think that the rectangle support should be separated from cua
bindings, to something like rectangle-mode or visual-rectangle-mode.
