It reads weird Lisp and Scheme in the same list with the other languages: for instance, in that list, Lisp and Python looks two independent categories, but Scheme is a subcategory of Lisp. I prefer to introduce Scheme in the next sentence as follows:
I don't see what the new wording makes clearer, rather I think it makes it unclear. The list specifies _languages_, Lisp being one (GNU Emacs Lisp and Common Lisp being the ones refered to), and Scheme being another. Not language "categories".
