Thank you, that works.  David's "[^z-a]" works as well (it's really
smart!) and is shorter, I prefer this if there are no
contraindications, e.g., if "[^z-a]" is treated as an invalid regex in
some Emacs versions.

I'd like to match the regex exactly from point to mark position, much
like  \`...\'  in `string-match'.  `re-search-forward' treats `\'' as
"end of the buffer" also when the `bound' argument is used.  `\='
matches the empty string at point, but I found no ways to match the
empty string at `bound' position.  Anyway, this isn't essential, `\='
does at least half of the job.

After some testing I'm not persuaded it's a good idea to remove
`TeX-math-close-double-dollar'.  E.g., a plain TeX user probably want
to set `TeX-electric-inline-math' to '("$" . "$"), but if point is
after the third dollar in the following line
  $$ a+b=c $
pressing another time `$' will insert a couple of dollars because
there (texmathp) returns nil.  This isn't the expected behavior and
`TeX-math-close-double-dollar' does a better job.

I'm sending the full patch for `tex.el'.  I'll update `doc/auctex.texi' as well.

In my .emacs I define the following function
--8<---------------cut here---------------start------------->8---
(defun TeX-toggle-electric-inline-math ()
  "Toggle the value of `TeX-electric-inline-math'."
  (interactive)
  (cond
   ;; "\(...\)" to "$...$"
   ((equal TeX-electric-inline-math '("\\(" . "\\)"))
    (setq TeX-electric-inline-math '("$" . "$"))
    (message "`TeX-insert-dollar' now inserts \"$...$\"."))
   ;; "$...$" to "$"
   ((equal TeX-electric-inline-math '("$" . "$"))
    (setq TeX-electric-inline-math nil)
    (message "`TeX-insert-dollar' now inserts \"$\"."))
   ;; Anything else to "\(...\)"
   (t
    (setq TeX-electric-inline-math '("\\(" . "\\)"))
    (message "`TeX-insert-dollar' now inserts \"\\(...\\)\"."))))
--8<---------------cut here---------------end--------------->8---
I don't know if it's worth adding it to AUCTeX, I hope it will be
useful to someone reading this message.

Completely unrelated, can I reference gmane threads in ChangeLog?

Bye,
