In which format does add-apt-repository add PPA repository in 22.04 by default?

E.g. if you run

sudo add-apt-repository -P s.jansen/gogglesmm

will the repository be added in one-line-style format or in DEB822-style format?

22.04

    This is easily tested by starting up a 22.04 container using Docker, Podman, LXC, systemd-nspawn, etc., etc.:

    $ lsb_release -sc
jammy
$ head /etc/apt/sources.list.d/s_jansen-ubuntu-gogglesmm-jammy.list
deb https://ppa.launchpadcontent.net/s.jansen/gogglesmm/ubuntu/ jammy main
# deb-src https://ppa.launchpadcontent.net/s.jansen/gogglesmm/ubuntu/ jammy main

    Even if you didn't have a container, you could inspect the changelogs for a recent version of software-properties-common (the package which provides the add-apt-repository command), where you'd see that all entries about deb822 support came well after 22.04 was released (the oldest entry seems to be from March 2023).
