[AUCTeX] TeX-auto-generate confused by comments

[Tristan Miller]

Dear all,

In a separate thread I was advised to run TeX-auto-generate to generate
style hooks for the custom classes I'm using.  I discovered that this
command seems to get confused by comments in the optional argument to
\RequirePackage.  For example, take the following class file:

\NeedsTeXFormat{LaTeX2e}
\LoadClassWithOptions{article}
\ProvidesClass{foo}[2017/09/07 v0.1 test class]
\RequirePackage[
backend=biber, % here is a comment
]{biblatex}

Running TeX-auto-generate on this class file results in the following
style file, which fails to account for the use of biblatex:

(TeX-add-style-hook
 "foo"
 (lambda ()
   (TeX-run-style-hooks
    "latex2e"
    "article"
    "art10"))
 :latex)

However, removing "% here is a comment" and re-running
TeX-auto-generate results in the following, which looks more correct:

(TeX-add-style-hook
 "foo"
 (lambda ()
   (TeX-add-to-alist 'LaTeX-provided-package-options
                     '(("biblatex" "backend=biber" "")))
   (TeX-run-style-hooks
    "latex2e"
    "article"
    "art10"
    "biblatex"))
 :latex)

Am I correct in assuming that this is a bug?  I know that a lot of
people use comments like this to explain the purpose of (sometimes very
obscure) package options.

Regards,
Tristan
