    Report a sensible error if no secret file provided.
    
    If you run doit.exe with an empty command line, it wouldn't actually
    _notice_ the lack of a shared-secret file name on the command line,
    which is an easy mistake because it's processing its arguments as a
    single string instead of an argv. So it would simply pass the empty
    string to fopen, which would return NULL - but _not_ set a Windows
    error code, leading to a rather silly box saying
    
      DoIt shared secret error
    
      Unable to open "": Error 0: The operation completed successfully.
    
    Now it prints a much more sensible error message in that situation!
