Subject: Update cli_printMessage.sh:


    - Start using MESSAGE_WIDTH variable.

    - Start using space character in its octal form (040) to represent
      the separation needed after colons (:) in request-lines and
      questions. We can not use mere space here, because this function
      might be called from itself more than once and trailing and
      leading spaces passed as MESSAGE will be lost.
