    This is why the status code does exist. I think it does not make a
    difference here if the scanner scans a new page, the backside of a page
    or gets the image from memory. It is not a hack.

    When XSane runs in ADF mode, it does print the error message "no docs"
    when the first sane_start returns with SANE_STATUS_NO_DOCS.
    When there is at least one page scanned XSane does print a message
    "# pages scanned".
