ConditionalExpression indentation

[belav]

The changes for #76 seem to indent too much in some real world code.

// new version
            Doc sections = node.Sections.Count == 0
                ? " "
                : Docs.Concat(
                        Docs.Indent(
                            Docs.Concat(
                                Docs.HardLine,
                                Join(
                                    Docs.HardLine,
                                    node.Sections.Select(this.Print)
                                )
                            )
                        ),
                        Docs.HardLine
                    );
// old version
            Doc sections = node.Sections.Count == 0
                ? " "
                : Docs.Concat(
                    Docs.Indent(
                        Docs.Concat(
                            Docs.HardLine,
                            Join(
                                Docs.HardLine,
                                node.Sections.Select(this.Print)
                            )
                        )
                    ),
                    Docs.HardLine
                );

prettier appears to use the align doc type for this, to keep from adding too much extra indentation along with a whole lot of other logic for what to do.
