Fix some linebreak decisions in Google format.

Before:
f(aaaaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaa +
  aaaaaaaaaaaaaaaaaaaa);
aaaaaaa(aaaaaaaaaaaaa, aaaaaaaaaaaaa, aaaaaaaaaaaaa(aaaaaaaaaaaaaaaaa,
                                                    aaaaaaaaaaaaaaaa));

After:
f(aaaaaaaaaaaaaaaaaaaa,
  aaaaaaaaaaaaaaaaaaaa,
  aaaaaaaaaaaaaaaaaaaa + aaaaaaaaaaaaaaaaaaaa);
aaaaaaa(aaaaaaaaaaaaa,
        aaaaaaaaaaaaa,
        aaaaaaaaaaaaa(aaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaa));
