That might indicate that you are working in a field of math where there
are few exponentiated expressions which are already exponentiated. But
I don't think that exponents have grown out of vogue in general. ;-)

Come on, reverting this broken feature doesn't move us back to the
middle ages.

"In fact, those will be displayed in a completely wrong way!" would be
more correct.

Let's use this compromise: I have already removed the feature but you
are free to put
--8<---------------cut here---------------start------------->8---
(require 'font-latex)
(defun font-latex-match-script-chars (limit)
(let ((p (point)))
(and (re-search-forward "[_^]" limit t)
(let ((pos (match-beginning 0)))
(and (font-latex-faces-present-p 'font-latex-math-face pos)
(not (font-latex-faces-present-p '(font-lock-constant-face
font-lock-builtin-face
font-lock-comment-face
font-latex-verbatim-face)
pos))
;; Check for backslash quoting
(not (let ((odd nil)
(pos pos))
(while (eq (char-before pos) ?\\)
(setq pos (1- pos) odd (not odd)))
odd)))))))
(add-to-list 'font-latex-keywords-2
'(font-latex-match-script-chars
(0 '(face font-latex-math-face invisible t)))
t)
--8<---------------cut here---------------end--------------->8---
into your ~/.emacs, and then scripts will be hidden again. (You don't
need to configure `font-latex-fontify-script'. Just let it on its
default value of t for Emacs.)
Bye,
