Current script shows message:
 Don't forget to add the subject and message to ...
 Then perform:
 git send-email -to xen-devel@lists.xenproject.org ...
which has wrong option '-to'.
It may be confused for user.

Set double dashes for longer options to avoid that.

For some reason, the git send-email still works as expected with the use
of single dash instead of two even if this isn't documented.
