    explicitly direct output to stdout if '-' is given as a file name

    There is no mention in the POSIX documentation that fprintf() will
    print to stdout if the NULL pointer is passed as the stream.
    And, indeed, the current implementation triggers a segmentation fault
    if invoked as '-statdump -'.
