[openssl-dev] s_client uses SSL_write(..., 0) for renegotiation?

Should s_client really be using a zero-byte-length SSL_write(...) as a
followup to SSL_renegotiate(...)?  All versions of the man pages on the
OpenSSL web site state this will yield undefined behavior (which I find
odd, but whatever).

Is SSL_do_handshake(...) more appropriate?
