I've just fixed a complex Emacs Lisp program using `error' in batch mode
where messages of the "Exception: 'foo'" kind were turned into
"Exception: ‘foo’", leading to a crash in the test rig written in as it
did not expect non-ASCII output.  I find this inacceptable behavior.
Why should printing one thing print something entirely different from
what has been specified?

I've learned that there is a `text-quoting-style' variable that controls
this behavior, however both its docstring and the corresponding news
entry suggest that there is no way to disable the post-processing.  On
top of that they don't mention that the simplest way to make things look
like they previously did is to set it to `grave`.  Is there any reason
this is not documented?  More importantly, if that is the truth, why is
there no flag to disable that post-processing?

Thanks for the hint, I'm on Emacs 25.1 where the behavior is as
described.  As you've pointed out, 25.2 does not take
`text-quoting-style' into account for both `message' and
`format-message', additionally to that the (incompatible) change has
been documented and the docstring updated to clarify that `grave` is the
setting to disable post-processing.
