Code review comment for ~awe/snappy-hwe-snaps/+git/network-manager:cellular-doc-improvements

Just pushed a new version. Thanks everyone for the detailed review!

@Kyle, the only suggestion I nak'd was:

"causes ... to be preferred" is wordy. maybe like this: "...created with a lower priority than E or Wifi routes, which are therefore preferred..."

I found your suggested working, just as wordy as the original. ;)-
