The output of this CI script leaves much to be desired: it is
output from 'diff' with little clarity on what exactly is wrong.
The proper fix is to make the output clear and readable:
podman containers --help lists a 'foo' subcommand that
is not present in docs/podman-containers.1.md
Doing this in bash would take many hours and be fragile
gibberish code. This does not seem worth the effort: the
likely case is that breakages reported by this script
will be due to a newly added subcommand, and the PR
author will find it obvious what to do. Ergo, plan B:
if the test fails, display a blurb at the end describing
how to interpret results. Three minutes' effort, plus
five for writing this commit message.
