Oh I am really sorry for not even responding to this PR. I would have normally said at least something, but I don't have this project too much in my radar and totally forgot about it.

I threw tkn to GitHub to share it at the petition of some people, but in reality I evolve it in private copies conference after conference with ad-hoc things that are not generalizable. That is because I have never sit down to make it something with a vision and clear design. That paralizes me when dealing with patches, because... there is no direction or design constraints to follow in my head.

This might change some day, in which case I might port some of these.

Please excuse, and thanks for the patch.
