[PATCH] Use setq-local compatible with Emacs 26

[Radon Rosborough]

Hello all,

I noticed that commit e625dc05 of 2022-02-24 made AUCTeX incompatible
with Emacs 26 by using the variadic form of setq-local that was
introduced in Emacs commit 88f0c566 of 2019-10-11 and first released
in Emacs 27.1. The current version of AUCTeX still lists Emacs 25.1 as
the minimum compatible version (based on file auctex.el.in from commit
aae80c47 of 2022-04-14), so I am guessing this was unintentional.
Anyway, it triggers a byte-compilation error in my configuration, so I
have attached a patch to fix the issue.

I have never contributed to a Savannah project before, so please let
me know if the formatting needs to be adjusted, or if I need to submit
elsewhere.

Thanks,
Radon Rosborough

Hi 

Please consider

In which I run  LaTeX-fill-environment

That seems to me also a strange result. Using an array and a pmatrix is
odd I  confess, but I received this file in that form.
Any ideas what to do?

\begin{equation}\label{Mn}
