Avoid confusing indentations for chained function calls.

Basically treat a function with a trailing call similar to a function
with multiple parameters.

Before:
  aaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
      aaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaa))
      .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa();

After:
  aaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
                           aaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaa))
      .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa();

Also fix typo.
