Function whine_about_eof

io.c:217–233

It's almost always an error to get an EOF when we're trying to read from the * network, because the protocol is (for the most part) self-terminating. * * There is one case for the receiver when it is at the end of the transfer * (hanging around reading any keep-alive packets that might come its way): if * the sender dies before the generator's kill-signal comes through, we can end * up here

 * listing was not terminated, so we must ignore an EOF error in that case and
 * exit.  In this situation, kluge_around_eof will be > 0. */
