@Cleop - please review to ensure the changes we've made are the right ones

@iteles - just adding you so you can cast your eye over the new copy

@rub1e, hoorah! 🎉 It's review time! 👀

I couldn't help but notice that there isn't an in-progress label on this pull request and a Reviewer
has been added...makes me think that this pull request is ready for review 🤔

To save you time ⏳ I've added the Reviewer as an Assignee and I've added the awaiting-review
label - automatically - just like magic! 🎩 🐰 ✨. Please correct me if I'm wrong, but if I got it right
this time I hope it helps you! 😄

Any questions, complaints, feedback, contributions?

If you prefer, you can also send us anonymous feedback: https://dwyl-feedback.herokuapp.com/feedback/new

Gosh isn't dwyl-bot clever!

Why did it admonish me twice though - is that because I added two reviewers? Is this the sort of behaviour I should open an issue about?

[SimonLab]

@rub1e an issue already exists for dwylbot dwyl/dwylbot#129, I need to sit down and review/clean the dwylbot code

[Cleop]

Amazing 😄 nice one Rubie!

Made a couple of tiny (pretty much formatting) changes, thanks @rub1e !
