commit e29bb83479cc567b4bb414dc55148ec06a30a115
Author: Lingmo Zhu <zlm2006 at gmail.com>
Date:   Tue Jul 25 18:00:44 2017 +0800

    Remove the obsolete misleading comment and code related to it.
    
    The comment "The following should not return 1, otherwise, things
    are very strange" is from the very first commit of OpenSSL. The
    really meaning of the comment is if the identical session can be
    found from internal cache after calling get_session_cb but not
    found before calling get_session_cb, it is just strange.
    
    The value 1 was originated from the old doc of SSLeay, reversed
    from the actual return value of SSL_CTX_add_session().
    
    Anyway either return value of SSL_CTX_add_session() should not
    interrupt the session resumption process. So the checking of
    return value of SSL_CTX_add_session() is not necessary.
