Comment(by nickm):

 Hm.  At first I was going to suggest that this go into 0.2.3, but it looks
 like this is actually triggerable: just GETCONF a key that's exactly the
 right length.

 I don't think that send_control_event_impl change is right: it looks like
 that function actually _did_ ensure that its strings had a CRLF before
 sending to send_control_event_string, and that some of its callers rely on
 this feature: Look at conrol_event_general_status and the functions that
 call it.
