It's actually a standard way to separate groups of arguments, e.g.

    touch -- -a
    rm -- -a

will create and remove a file called -a, and

    startx -geometry +1+1 -- -depth 16

passes "-geometry +1+1" to the client and "-depth 16" to the server.

True, but this would break any existing scripts.

Yup, same problem.
