People usually make changes to the system to make it "more useful"
and/or "more helpful", and almost never to make it "less helpful".
Phrases you would use to explain why the failures become more
helpful with this change (compared to without) would help to promote
it in the "git shortlog --no-merges" output for the next release.
E.g. "make X failures stand out more", "make X failures gramatically
correct", "show X failures more concisely", etc.

I think we saw changes to upgrade actions/checkout@ in another
topic, and it seems that we have missed this one even though we
should have upgraded it the same way as other files in the same
directory?  Shouldn't this hunk be a separate topic on its own,
or at least a separate patch on its own in the series?

Is it safe to assume we run Bash here, or can GitHub start using
other shells that lack the Bash-ism shell arrays and we should
protect against such future?

I suspect that we are already depend on <<< Bash-ism, so one more
dependency to Bash-ism is not a problem here?  I dunno.

Thanks.
