I think Dscho's suggestion was to sign-off when you commit, not when you
format-patch.  It won't make any difference either way to me nor other
people who reads the list, because nobody can tell which way you used by
looking at your e-mail, but it is a good habit to get into if you work on
git or the kernel.
