Before:
aaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaa).aaaaaaaaaaaaaaaaa(
    aaaaaaaaaaaaaaaaaaaaa).aaaaaaaaaaaaaaaaaaa(
    aaaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

After:
aaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaa)
    .aaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaa)
    .aaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaa,
                         aaaaaaaaaaaaaaaaaaa,
                         aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
