Normal indent for last element of builder-type call.

In builder type call, we indent to the laster function calls.
However, for the last element of such a call, we don't need to do
so, as that normally just wastes space and does not increase
readability.

Before:
aaaaaa->aaaaaa->aaaaaa( // break
                  aaaaaa);
aaaaaaaaaaaaaaaaaaaaa->aaaaaaaaaaaaaaaaaaaaaa
    ->aaaaaaaaaaaaaaaaaaaaaaaaaa(
        aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

After:
aaaaaa->aaaaaa->aaaaaa( // break
    aaaaaa);
aaaaaaaaaaaaaaaaaaaaa->aaaaaaaaaaaaaaaaaaaaaa->aaaaaaaaaaaaaaaaaaaaaaaaaa(
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
