git-send-email: Fix authenticating on some servers when using TLS.

rshearman · gitster · commit 9d1ccf5e640b · 2008-07-09T15:53:10.000-07:00
Send HELO again after a successful STARTTLS command to refresh the list of extensions. These may be different to what is returned over a clear connection (for example the AUTH command may be accepted over a secure connection, but not over a clear connection). Furthermore, this behaviour is recommended by RFC 2487 (http://www.ietf.org/rfc/rfc2487.txt).
