Actually there seems to be no difference for those sites. Without this
patch SChannel on Windows 7 will try to connect using TLSv1.0 first and
won't be able to connect to a SSLv3 site since TLSv1 does not support
downgrading to SSLv3. This means that the patch basically enables
TLSv1.1 and TLSv1.2 on top of TLSv1.0 and does not have any affect with
regards to SSLv3 which needs to be explicitly enabled using --sslv3.
