w(1) behaviour has changed with brien commit in w.c revision 1.48.
Funny, but looks like '-n' options works right after commit, not before.
The reason is utmp holds a host name and w(1) with '-n' flag _do_
resolve hostname back in IP address and without '-n' don't resolve it.
It's confised.
IMHO to be more robust, we should make utmp to hold an IP address
instead of a hostname and change all applications that use it. As bonus
it will fix a delay on login when resolving does not work. And last(1)
will show more useful IP address instead of changable hostname.
But I'm not sure about standards.
