I now understand better what happens, but I still haven't solved the problem.

First, the `TeX-clean-default-intermediate-suffixes' variable is defined in
tex.el (l.2184, AUCTeX 12.2.0).  Then the `LaTeX-clean-intermediate-suffixes'
variable takes its value and appends it with more suffixes in latex.el (l.6061).

In my init.el, there are two more packages that add to the list: auctex-latexmk
and latex-extra.  latex-extra uses add-to-list and auctex-latexmk uses append.

So what I'd like to do is to append `LaTeX-clean-intermediate-suffixes' with
some more suffixes.  However, doing

(setq LaTeX-clean-default-intermediate-suffixes
        '(append LaTeX-clean-default-intermediate-suffixes
                 '("\\.dvi" "\\.ent" "\\.fmt" "\\.rel" "\\.rip" "\\.tags" 
"\\.vrb")))

does not work.  (Even if I completely comment out auctex-latexmk and
latex-extra.)

What is the proper way to append `LaTeX-clean-intermediate-suffixes', preserving
all the other additions to it?

I use use-package, if that makes any difference.  I put the setq in the :config
part after

(use-package latex
  :ensure auctex
  :mode ("\\.tex\\'" . LaTeX-mode)
  ...

Thanks!
