I have no specific license for this (sadly). I also think that it would be hard to make legal.

Tutorials and how-to sections are documentation, and IMHO would fall under such a restriction.

Artistic license probably allows any reformatting. Anywhere.

I have never seen a license that enforces style and/or formatting. I also think that using such a licence would make many companies forbid the use of such code.

My wish is not to enforce my style on real-life code. My docs just should how *I* think it should be done most efficiently and most maintainable, but code and code style consistency in any project is way more important than the code (style) of a single sub/method/class.

However I would love to see the rest of the world to use my style, I know it is not going to happen. People think different.

My post was aimed at blogs, documentation, learning/teaching content that just copies from the documentation but then alters the style. However I understand that learning materials should also be consistent, I find this unacceptable.
