@matti-kariluoma, I just realized that this is your first PR here, so I'd like to say thank you for this!

If you need anything clarified, feel free to ask.

[matti-kariluoma]

I removed candle from my system, made the requested changes then reinstalled. All working!

[peterhoeg]

Looks good - as the last thing, can I get you to squash the commits so we end up with one commit adding you to the maintainer list and another that has all the changes for the actual software?

[matti-kariluoma]

Looks like I can't resolve the last change request, probably due to the rebase... Do I need to create a new pull request?

[matti-kariluoma]

Alright, that should be all of the requsted changes. Squashed down to two commits as well

Looks great! Thank you.
