Parameter pack rendered with two `...`

[alandefreitas]

The signature is rendered with two ellipses after a parameter pack argument type:

template<
    class T,
    class... Keys,
    class... Args>
T&
emplace(Args...&&... args)
requires get_key<T>::value;

Minimal example:

template<class T>
struct get_key
{
    static constexpr bool value = true;
};

template<
    class T,
    class... Keys,
    class... Args>
T&
emplace(Args&&... args)
    requires get_key<T>::value
{
    // implementation not important
    static T obj{};
    return obj;
}

well there are two packs after all. this is probably due to how mr docs converts SFINAE via function parameter into requires (which is pretty cool by the way)
