Fixes a bug with pasting expressions with multiple lines.
Example: Coping Code:
            return Enumerable.Range(1, 10)
                    .Where(true)
                    .Where(true)
                    .Where(true)
                    .FirstOrDefault();
Pasting:
            return Enumerable.Range(1, 10)
                .Where(true)
                    .Where(true)
                    .Where(true)
                    .FirstOrDefault();t();
