I'm not certain. Consider client running Fedora (without the patch)
connecting to server running Debian. I think it should be upstream if it
not disrupts other systems.

This is probably about how should netcat behave and which implementations

I think adding `-q 0' for nc execution upstream should not hurt in either case.
