    Just updated to HEAD and I saw the recent ifconfig, usb ethernet,
et all changes:

$ ifconfig
usbus0: flags=0<> metric 0 mtu 0
usbus1: flags=0<> metric 0 mtu 0
usbus2: flags=0<> metric 0 mtu 0
usbus3: flags=0<> metric 0 mtu 0
msk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=c011b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,TSO4,VLAN_HWTSO,LINKSTATE>
	ether 00:1d:60:b6:eb:97
	inet 192.168.20.3 netmask 0xffffff00 broadcast 192.168.20.255
	media: Ethernet autoselect (1000baseT
<full-duplex,flowcontrol,rxpause,txpause>)
	status: active
usbus4: flags=0<> metric 0 mtu 0
usbus5: flags=0<> metric 0 mtu 0
usbus6: flags=0<> metric 0 mtu 0
usbus7: flags=0<> metric 0 mtu 0
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
	options=3<RXCSUM,TXCSUM>
	inet 127.0.0.1 netmask 0xff000000
$ ifconfig -l
usbus0 usbus1 usbus2 usbus3 msk0 usbus4 usbus5 usbus6 usbus7 lo0

    I don't have any USB ethernet devices, so I would expect usbus, et
all to be blank, but this would break a few (dumb) scenarios we have
at my work where it goes and looks at ifconfig -l (of course I've
tried convincing others to use ifconfig -l inet instead, but that was
to no avail).
    This could potentially break other dumb scripts as well.
    So the question is: what are we gaining with this additional, terse output?
Thanks,
-Garrett
