SSLv23 understands SSLv2, SSLv3 and TLSv1. When used in a client it uses
SSLv2 but tells the server it can understand the other ones too. Check
out the SSL_CTX_new manpage for a lot more details.

I agree, TLSv1 is a lot better but there's no point in breaking
backwords compatibility when you don't have to. Also, given my problems
with 7.3's SSL I'd be surprised if a lot of people who use it have made
the switch.
