Improve indentation of builder type calls.

In builder-type calls, it can be very confusing to just indent
parameters from the start of the line. Instead, indent 4 from the
correct function call.

Before:
aaaaaaaaaaaaaaaaaaa()->aaaaaa(bbbbb)->aaaaaaaaaaaaaaaaaaa( // break
    aaaaaaaaaaaaaa);
aaaaaaaaaaaaaaaaaaaaaaa *aaaaaaaaa = aaaaaa->aaaaaaaaaaaa()->aaaaaaaaaaaaaaaa(
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
    ->aaaaaaaaaaaaaaaaa();

After:
aaaaaaaaaaaaaaaaaaa()->aaaaaa(bbbbb)->aaaaaaaaaaaaaaaaaaa( // break
                                        aaaaaaaaaaaaaa);
aaaaaaaaaaaaaaaaaaaaaaa *aaaaaaaaa = aaaaaa->aaaaaaaaaaaa()
    ->aaaaaaaaaaaaaaaa(
        aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
    ->aaaaaaaaaaaaaaaaa();
