Code review comment for ~bryce/ubuntu/+source/exim4:merge-v4.93-13-focal

The merge is fine, our Delta is simple and retained correctly.

The merged version in Debian only has 4 backported fixes and one moved file.
All of them seem valid fixes to me and do not imply the need for an FFe.

Formalisms (changelog, update-maintainer, ..) are all good as well.

+1 form me for an upload before Focal release.
