gpioctl enumerates non-switch cmdline args to stdout when
doing simple reads or writes.

root@duovero:~ # gpioctl 110
0/110
0
root@duovero:~ # gpioctl 110 1
0/110
1/1
root@duovero:~ # gpioctl 110
0/110
1

It's confusing and not documented.

I'm suggesting removing those lines so the output looks like

root@duovero:~ # gpioctl 110
1
root@duovero:~ # gpioctl 110 0
root@duovero:~ # gpioctl 110
0
