Code review comment for ~mfo/ufw:lp1946804

If you send up a PR for debian/master, then I'll upload to Debian and sync to the devel release. Don't worry about ubuntu/master (I only update that if the latest release is different from debian/master, so it is a little out of date atm).

For the Ubuntu SRUs, if you were feeling (even more) industrious, it would be nice to pull in 632cda034f7b96d07667b06d39b6eb396c0e611f to fix https://launchpad.net/bugs/1933117 for 18.04 and later. By all means don't feel that this is required, but the fix is in Debian, impish and the snap already, so if this sounds like something you'd like to do, it just needs the SRU paperwork and processing.
