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.
