Revert chain indentation in an argument list

[belka-ew]

Fixes the indentation of arguments after a function chain (see the tests for examples).

This fix works only with --single_indent=true. The reason is that function chains aren't aligned properly without --single_indent. For example the following code:

class C {
    void f()
    {
        if (true) {
            f(
                    array.map!(a => a.prop)
                        .array
                        .to!string,
                    __FILE__,
                    __LINE__);
        }
    }
}

is formatted as

class C
{
    void f()
    {
        if (true)
        {
            f(
                    array.map!(a => a.prop)
                    .array
                    .to!string,
                    __FILE__,
                    __LINE__);
        }
    }
}

So I think it is a different problem.

shouldn't there be a new line after the .map,? Or at least wrap after the 3rd __FILE__ and not after the 5th (because the other lines below also wrap around that column)

[belka-ew]

Yeah, it is how line breaks are currently added. It was the main reason we wanted to have --keep-line-breaks, so such things can be adjusted manually because in the complicated code it is difficult to calculate the right way to add line breaks (if there is the right way).

looks good for what it fixes
