I have made new function to replace `command-stream-in-out' with:

(defun rcd-command-output-from-input (program input &rest args)
  "Returns output from PROGRAM INPUT with optional ARGS"
  (let* ((output (with-temp-buffer
		  (insert input)
		  (apply #'call-process-region nil nil program nil t nil args)
		  (buffer-string))))
    output))

and I have to use `apply' to get it working. I think this is solved.

I found a tip here:
https://stackoverflow.com/questions/629699/common-lisp-working-with-rest-parameters

As now I got it that `args' is a list.
