Can someone look at this PR, please? I have no idea why the checks are not successful; I'm a sporadic contributor with correspondingly sparse knowledge of how to pursue this - but the improvement is both trivial and useful (to us, posisbly others).

Doing this changes nothing..? I have never used bundle or any of these tools, so I feel extremely noob right now..

Dum-did-um @smortex any ideas? :)

I updated REFERENCE.md and squashed the commits.

The unit test needs some work still.

[ltning]

What kind of work? Anything I can/should do?

[kenyon]

@ltning yes, see the test failure. Something about the matching isn't right.

[ltning]

Sorry @smortex - I don't understand what's still failing here. I see it passing on most, but not all, test runs.

Ah, it's the same error we're seeing in #1579 (@C24-AK), but seeing it on Puppet 7 there versus 8 here. So it doesn't have to do with the changes in these pull requests.
