`M-q' uses tree-sitter now?

[Eduardo Ochs]

Hi list,

I am running an Emacs30 that I git-pulled and compiled a few hours ago
- its emacs-repository-version is

  "5a344d90c53d681ed98ab03ad3e218a3c6561108"

and I noticed that if I type `M-q' (`fill-paragraph') in a buffer in
emacs-lisp-mode I get this error:

  prog-fill-reindent-defun: Symbol's function definition is void:
  treesit-parser-list

I grepped the Lisp sources and `treesit-parser-list' is only mentioned
in two files: "treesit.el" and "progmodes/prog-mode.el". I tried

  (require 'prog-mode)
  (require 'treesit)

and `M-q' to see if the error would go away... but nah, same thing.
So I thought that this would be worth reporting...

  Cheers =/,
