Make should set optreset to one before it calls getopt() with a new
set of args.

    o Removed unnessisary forward declaration for MainParseArgs()

    o Use optreset global variable to inform getopt() that we are
      parsing another arg list.

    o Cleanup handling of remaining arguments after getopt()
      completes parsing arguments.  There is no reason to restart
      getopt() for single dash case, just ignore it.  And update
      comment to reflect code.

    o Removed missleading comments.
