Problem:
Some steps in :Tutor don't work on Windows.
Solution:
Add support for `{unix:...,win:...}` format and transform the Tutor contents
depending on the platform.
Fix https://github.com/neovim/neovim/issues/24166
Problem: When double clicking a line starting with a #, the code assumes
there is a fold there and tries to close it, resulting in an error if
there isn't a fold.
Solution: Check foldlevel before performing "zc".
