clang-format: Fix bug in wrapping behavior of operators.

Before (even violating the column limit):
  auto Diag =
      diag()
      << aaaaaaaaaaaaaaaa(aaaaaaaaaaaa, aaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaa);

After:
  auto Diag = diag() << aaaaaaaaaaaaaaaa(aaaaaaaaaaaa, aaaaaaaaaaaaa,
                                         aaaaaaaaaaaaaaaaaaaaaaaaaa);
