'notation' isn't the correct term about requiring masks in OpenBSD,
nowhere uses the stupid "10.20.30.40/255.255.240.0" format (unless you
count ports - e.g. Samba).

The places mentioned do need IP and netmask as values though, no way
to use a prefix instead.

ifconfig is an easy example, you can't "ifconfig foo0 inet 10.20.30.40/20",
you must instead type "ifconfig foo0 inet 10.20.30.40 netmask 255.255.240.0"
(or 0xfffff000, if you prefer something easier to type).

But permit prefixes here, and I'm sure some people will try and use
them in hostname.if some way or other, support there means either changing
format or making /etc/netstart more (too?) complicated. As usual, there's
more to think about than how to add the features.
