Hi all,

say you have a .tex file like this:

--8<---------------cut here---------------start------------->8---
\documentclass[11pt]{article}

\usepackage{mypackage}

\begin{document}
foo
\end{document}

%%% Local Variables:
%%% mode: LaTeX
%%% TeX-master: t
%%% End:
--8<---------------cut here---------------end--------------->8---

loading mypackage.sty and you have also written an AUCTeX style file
mypackage.el which looks like this:

--8<---------------cut here---------------start------------->8---
;;;   -*- lexical-binding: t; -*-

(TeX-add-style-hook
 "mypackage"
 (lambda ()
   (TeX-add-to-alist 'LaTeX-provided-class-options
                     '(("article" "11pt")))
   (TeX-add-to-alist 'LaTeX-provided-package-options
                     '(("babel" "english")
                       ("booktabs" "")
                       ("fontspec" "")
                       ("geometry" "a4paper")
                       ("graphicx" "")
                       ("lastpage" "")
                       ("microtype" "activate")
                       ("parskip" "")
                       ("siunitx" "")
                       ("tabularx" "")
                       ("titlesec" "pagestyles")
                       ("xcolor" "svgnames")
                       ("xspace" "")))
   (TeX-run-style-hooks

    "babel"
    "booktabs"
    "fontspec"
    "geometry"

    "microtype"

    "tabularx"
    "titlesec"
    "xcolor"
    "xspace"))
 TeX-dialect)
--8<---------------cut here---------------end--------------->8---

IIUC, the hand-written additions to `LaTeX-provided-package-options' and
`LaTeX-provided-class-options' are never activated in the .tex file.  I
played with moving these forms around from `LaTeX-auto-cleanup':

  (setq LaTeX-provided-class-options nil)
  (setq LaTeX-provided-package-options nil)

but no avail.  The best solution I can currently offer is:

--8<---------------cut here---------------start------------->8---
diff --git a/latex.el b/latex.el
index 3a32c4e7..8b35851a 100644

I.e., adding the variables to `TeX-normal-mode-reset-list' and deleting
the forms inside `LaTeX-auto-cleanup'.  Am I missing something?

Best, Arash
