I am confused. How can we switch back to SSLv23_method and still be
compatible with TLSv1_method. Does SSLv23_method support both?
The SSL author didn't like SSLv23_method (especially SSLv2) and I am not
confident to question his decision. We will just have to break backward
compatibility with pre-7.3 clients. No one else has mentioned it as a
problem, and in fact most have probably already upgraded to 7.3, so we
should be OK.
