Leading comments interfering with breaking InitializerExpression

[belav]

Look into roslyn/src/Compiles/CSharp/Portable/Binder/Semantics/Operators/BinaryOperatorEasyOut.cs
It has some really long line that isn't breaking.

I've reproduced the problem

class ClassName
{
    private SomeClass[,] someClass = {
        // leading comment should not interfere with the next line breaking
        { longValue______________________________, longValue______________________________, longValue______________________________ },
        {
            longValue______________________________,
            longValue______________________________,
            longValue______________________________
        }
    };
}
