Fix formatting issue with builder-type calls.

Before:
->aaaaaa()->aaaaaaaaaaa(aaaaaaaa()->aaaaaa()->aaaaa() - aaaaaaaaa()->aaaaaa()
                                                             ->aaaaa());

After:
a->aaaaaa()->aaaaaaaaaaa(aaaaaaaa()->aaaaaa()->aaaaa() -
                         aaaaaaaaa()->aaaaaa()->aaaaa());
