Yes, that is for the 'Supported Point Format Extension',
which the RFC says is fine to send in the ServerHello, but the RFC
doesn't say anything about the `Supported Elliptic Curves Extension`
being sent in a ServerHello, only in a ClientHello.

I'll try your patch, although I admit that the complexity of it is a
little beyond my understanding.
