Sample:

public class Test {

    Test a() {
        return this;
    }

    String b() {
        return null;
    }

    static void test() {
        new Test()
                .a()
                .b(); // invoke "Assign Return Value to New Variable" hint
    }

}

Once the hint is invoked, all three lines are indented - but only the first one should be.

Thanks.
