Netcat usage example for alternative versions

[johnadamson]

The version of netcat installed by Ubuntu 17.04's package archive (1.10-41) exhibits slightly different behavior than the version typically installed by Homebrew on macOS. nc localhost 8377 ends up causing an annoying block when sending bytes into Clipper. As a long time macOS user, I instantly noticed the difference.

Digging into the godoc for os.Copy reads

Copy copies from src to dst until either EOF is reached on src or an error occurs.

A slightly different usage of nc -N localhost 8377 exhibits the behavior I am used to. It would be helpful to have a mention in the documentation for others who may not be getting a very good user experience.

I'm a long-time fan of Clipper. Thanks for making such an awesome tool!

Thanks for reporting this and figuring out the workaround. Feel free to submit a PR if you'd like, or I'll get to this at some point when I have cycles for it.
