Should not the format argument be corrected to have valid @displaymath 
snippet instead?

Thank you, Max!  See, this happens when I write code 10 minutes before going to
bed: incorrect code and no tests, both equally bad.

Please see the attached patch.

Rudolf, I am afraid there is another obstacle till your step to improve 
Org may be completed.

In emacs-26 `string-join' is defined in subr-x.el, but ox-texinfo.el 
does not have (require 'subr-x). Personally I see nothing bad in

    (format "@displaymath\n%s\n@end" math-example)

Historically subr-x was avoided in Org. Latest discussion:

I will leave the decision to the maintainers since I have no particular 
opinion. Alternatively you may use (mapconcat #'identity (list) "\n").

It is preferable to fix earlier added call to `string-join' in this 
file. The similar approach should be applied to the tests added by this 
patch.

... which concluded that it is safe to use subr-x.
If we need to add a require, so be it. I see no major downsides.

I do not mind.

Since content of subr-x.el consists of `defsubst' definitions, likely it 
is preferable to use

     (eval-when-compile (require 'subr-x))

All right, I added the 'require' to both files.  Better?
