And by the way, one can re-sign an arbitrary range of commits like this:

$ which git-sign
git-sign () {
	case $# in
		("0") range=HEAD  ;;
		("1") range=$1  ;;
		(*) echo "too many arguments" >&2
			return 1 ;;
	esac
	git rebase "$range" --exec "git commit --amend --no-edit --gpg-sign" || git rebase --abort
}
