I found a way. In my .emacs I put:
(defun my-indented-yank(indent)
  "Put indented region in the kill-ring"
  (interactive "p")
  (setq indent (cond ((eq indent 0) 1)
                     ((eq indent 1) 4)
                     (t indent)
               )
  )
  (indent-rigidly (region-beginning) (region-end) indent)
  (copy-region-as-kill (region-beginning) (region-end))
  (undo)
)

It looks like this satifies my demands. ;-}
In this way the default indent is 4. If I need an indent of one I can
use 'C-u 0'.

The only thing is that the 'GNU Emacs Lisp Reference Manual' says that
I should not use 'copy-region-as-kill'. I should use 'kill-new' or
'kill-append'. But those do not work with a region. What am I missing?
