 * merely moves a line containing the string does not change how many times the
 * string appears, so it is not reported. The commit that *introduced* the string
 * is, which is what makes `-S <name> --reverse` answer "where did this come
 * from".
 *
 * Compared against the first parent, or against nothing for a root commit, so
 * the objects a root commit adds all count as introduced.
