    scripts/add_maintainers.pl: set double dashes for long options
    
    Current script shows message:
     Don't forget to add the subject and message to ...
     Then perform:
     git send-email -to xen-devel@xxxxxxxxxxxxxxxxxxxx ...
    which has wrong option '-to'.
    It may be confused for user.
    
    Set double dashes for longer options to avoid that.
