Hi @FunFR, thanks for the PR. Can you please take a look at the used email addr? It isn't associated with your github profile.

Hi @FunFR, is it possible that you review the git history? It looks a bit wrong. If you need help with git, feel free to join our IRC channel #voxpupuli on freenode, we are happy to help out.

Could you rebase this? If needed we can help.

[FunFR]

done ... Sorry for the delay :)

[ekohl]

No problem, sometimes life distracts you. Thanks for rebasing. Could you address the rubocop failure? Then I can merge it and include it in the release I want to make.

[ekohl]

Didn't you just add a second commit that fixed rubocop? I don't see it anymore.

[FunFR]

squash with rubocop patch

[ekohl]

Awesome, thanks!

Merging the tar PR also introduced a merge conflict.

[ekohl]

Looks like that didn't work. Did you pull in the latest master?

[bastelfreak]

Thanks for the rebase @FunFR !

[bastelfreak]

rebased it again
