Add net/prefixlen to the list of patterns (I think this is important
enough and not just a "lesser used pattern").
I will add this next round, but not this release.
Thanks for the feedback!
FYI, the net/prefixlen only works for IPv6, not IPv4 as you imply in this
report. I have, however, added net/prefixlen to the chapter (for IPv6).
This chapter will be on the Docs Beta CD and in the final product.
