clang-format: Fix regression caused by r237244.

Before:
  [call aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.
          aaaaaaaa];

After:
  [call aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa
          .aaaaaaaa];

This merely papers over the fact that we aren't parsing ObjC method calls
correctly. Also, the indentation is weird.
