Comment 6 for bug 325111

A thought:

Cisco IOS (routers) solved this by putting IPv6 addresses on their own line,
then indenting the following line so that the columns line up.

This is pretty easy for scripts that parse the output to accomodate, and visually it works, at least for me.

And since they have deployed a solution, it would be nice to be consistent....
