bug#32507: 27.0.50; text-quoting-style

[Helmut Eller]

There is no option to disable quote substitution in format-message.  In
other words, there should be a value for text-quoting-style for which
the following assertion does not fail:

(let* (;(text-quoting-style '<something>)
       (x "'`´‘’‚“”„")
       (y (format-message x)))
  (cl-assert (equal x y)))
