Enable Paredit for

• all Lisp-based major modes
• Emacs Lisp expressions in M-: (eval-expression).

What happens is:

1. submit-emacs-patch calls lm-maintainers on NEWS
2. lm-maintainers activates emacs-lisp-mode
3. emacs-lisp-mode activates paredit-mode
4. paredit-mode calls check-parens
5. check-parens errors out and leaves cursor somewhere
6. back in submit-emacs-patch, the mail is messed up

(with-eval-after-load 'lisp-mode
  (add-hook 'lisp-mode-hook #'paredit-mode)
  (add-hook 'emacs-lisp-mode-hook #'enable-paredit-mode)
  (add-hook 'eval-expression-minibuffer-setup-hook #'paredit-mode))
