Re: Wrong comment character when adding file local variables?

[Vitalie Spinu <spinuvit@gmail.com>]

All your examples are placed in fundamental mode. The comments are
treated by org and thus are correct, local variables are inserted
according to the major mode.

I don't how this could be easily fixed on org side, but you can solve it
straightforwardly with:

   (add-to-list 'auto-mode-alist (cons "NAME\\|DESC" 'R-mode))
