systat's default was changed to display names numerically,
Can says this was to avoid excessive blocking with the default
displays. However this left behind an ineffective -n flag and
no way to show names from the command-line (though there is
a yet-to-be-documented keyboard command to toggle this, 'n').
This diff adds -N to show names (keeping -n as is, it didn't
seem right to make -n behave oppositely from netstat).
ok?
