tex-mode.el dependency on (cl) every?

[David Kastrup]

I see that we have

+(put 'tex-verbatim-environments 'safe-local-variable
+     (lambda (x) (require 'cl) (every 'stringp x)))

Couldn't we rather use the equivalent
  (lambda (x) (null (delq t (mapcar 'stringp x))))
instead?

And why is this needed at all?  tex-verbatim-environments is only ever
passed to regexp-opt and member, so any old value will be _safe_.  So
it should be ok just to do

(put 'tex-verbatim-environments 'safe-local-variable t)

shouldn't it?
