bug#24868: 26.0.50; LaTeX-verbatim-macros-with-delims-local isn't taken into account

Starting from emacs -Q with (add-to-list 'auto-mode-alist '("\\.tex$" . LaTeX-mode)), opening the attached file produces incorrect highlighting.  This is due to LaTeX-verbatim-macros-with-delims-local not being applied properly.

Currently, the workarounds are:
* To not set LaTeX-verbatim-macros-with-delims-local locally (instead, put it in .emacs)
* To add \usepackage{polyglossia} to top of file (??! apparently polyglossia.el somehow refreshes the fontification?)
* Use an "eval:" prop line to refresh fontification:
  % Local Variables:
  % LaTeX-verbatim-macros-with-delims-local: ("fiatverb" "facadeverb" "sqlverb" "cverb")
  % eval: (progn (font-latex-set-syntactic-keywords) (font-latex-setup) (setq font-lock-set-defaults nil) (font-lock-set-defaults))
  % End:

None of these are very pleasant, unfortunately.  Can we add a hook to hack-local-variables that refreshes fontification appropriately?

(also: can we give LaTeX-verbatim-macros-with-delims-local a simple #'safe predicate?)

Thanks!
Clément.
