bug#37124: Lisp snippet for TeX-electric-math in manual

[Arash Esbati]

Hi all,

there is a lisp snippet in the manual for `TeX-electric-math'[1]:

    (add-hook 'plain-TeX-mode-hook
              (lambda () (set (make-variable-buffer-local 'TeX-electric-math)
                              (cons "$" "$"))))
    (add-hook 'LaTeX-mode-hook
              (lambda () (set (make-variable-buffer-local 'TeX-electric-math)
                              (cons "\\(" "\\)"))))

`make-variable-buffer-local' seems wrong to me, I think
`make-local-variable' is the intended function.  Am I missing something?
Otherwise I'd install the following patch:
