This will probably turn into a bikeshed argument, but....
I would have to heartily agree with you that this is the correct way
to do things. While it _might_ break something that parses arp(8)
output, always using two digits is how I have seen it done everywhere
else. You should be able to remove all of the colons and always have
a correct MAC address (12 digits), which is not the case currently.
