Code review comment for lp://qastaging/~afrantzis/mir/initializer-list-style

I can live with either way, and have started to like both of these colon-after-parenthesis styles as acceptable:
A(
    int a,
    float b,
    void* c) :
    mem1(a),
    mem2(b),
    mem3(c)
{
}

or, alternatively:
A(int a, float b, void* c) :
    mem1(a),
    mem2(b),
    mem3(c)
{
}

This is mostly because everything is aligned to the 4-space indents.
