This is the correct thing to do, vim-wise, although whether it has any impact depends on how the user has folding set up in vim. I confirmed that with the change, a folding setup that uses these variables works, whereas without the change, the same setup doesn't work.

Change only effects a file that has to be manually copied to the user's
~/.vim/syntax folder, so it won't impact jinja execution in any way.
