Implement an option -o ("Once only") that allows this netcat utility to terminate at the first EOF condition on local input (as opposed to waiting for the network end to shut down). Can be useful when talking to network servers that never drop the connection on their end, like an port 9100 printer server in my case. I've also submitted that to the OpenBSD maintainer, so in case they accept, we can later on undo my local patch.
