Fix bad formatting of overloaded operator definitions.

Before:
bool operator<
    (const aaaaaaaaaaaaaaaaaaaaa &left, const aaaaaaaaaaaaaaaaaaaaa &right) {
  return left.group < right.group;
}

After:
bool operator<(const aaaaaaaaaaaaaaaaaaaaa &left,
               const aaaaaaaaaaaaaaaaaaaaa &right) {
  return left.group < right.group;
}
