While looking into this I noticed that I left the following code in place:

In other words, we're still deciding whether to advertise -PLUS based
only on whether we support tls-server-end-point. Maybe all the
necessary features landed in OpenSSL in the same version, but I
haven't double-checked that, and in any case I think I need to make
this code more correct in the next version of this patch.
