I just did it for latex.el on the new core-latex-in-style-hooks branch.
However, there's a stupid problem I don't understand.  I open my a.tex
file which just contains:

--8<---------------cut here---------------start------------->8---
--8<---------------cut here---------------end--------------->8---

At that point, TeX-active-styles is

  ("art10" "article" "a" "latex2e" "LATEX" "LaTeX-core")

which seems right.  "LaTeX-core" is the new style hook I added.

But when I do

  M-: (TeX-remove-style) RET
  M-: (TeX-update-style t) RET

TeX-active-styles is

  ("art10" "article" "latex2e" "a" "NoVirtexSymbols")

Where is LaTeX-core and LATEX?  And how did "NoVirtexSymbols" arrive

Well, maybe.  But I think it wouldn't be bad to have relatively cheap
"forget & re-init" thingy.

Wouldn't (TeX-update-style t) do the same?

I wonder why TeX-normal-mode binds TeX-auto-save to t.  I guess there's
a reason for that, otherwise it wouldn't be there.
