[WARN] The commit is obviously broken and will not run the CI system. In
the rare case this is hit in a git bisect, just skip the commit.
The goal here was to make it trivial to review with the git option:
--color-moved=dimmed-zebra
It is required to move everything into one file because "exit 0" will
otherwise stop working as intended when the containing bash script is no
longer executed with "source ...".
If there is desire to split up 06_script_b.sh into logical chunks in the
future, it will also be easier after the following commit.
