Comment:

 Okay, so if I understand correctly, wanoskarnet is saying that our reading
 of the TLSv1_method() documentation and the SSLv23_method() documentation
 is wrong: that a TLSv1_method() client can connect perfectly well to a
 SSLv23_method() server, and vice versa.

 I'm attaching a quick&dirty test program to demonstrate this (using some
 code from libevent and some from the openssl docs).

 This doesn't mean that we need any changes in the code, except for fixing
 the comment to be correct.  I'll do that after I attach the demo code.
