/exec without controlling terminal 

Otherwise "/exec sh </dev/tty" takes over and catgirl must effectively
be killed to stop the madness;  with this diff:

	catgirl  input| /exec sh </dev/tty
	catgirl output| /bin/sh: cannot open /dev/tty: Device not configured
	catgirl output| Process exits with status 1

Do the same for `-C/Copy', `-N/notify' and `-O/open' alike.
