"patch in Post Scriptum" means I attached a small diff at the end of the
email, after my signature.  This will repurpose the eldoc-doc-buffer
function for non-interactive use, as we discussed.

OK.  Perfect.  For now you can use one of the solutions using internal
symbols.  I believe they are unlikely to change in the near future.

Actually, this _might_ be a non-problem.  You see, eldoc.el is a GNU
ELPA "core package" that works in older versions of Emacs as long as
they're >= 26.3.  You can see this in the header of the eldoc.el file:

   ;; Package-Requires: ((emacs "26.3"))
    
   ;; This is a GNU ELPA :core package.  Avoid functionality that is not
   ;; compatible with the version of Emacs recorded above.

So if you can arrange for emacsspeak to either use package.el ELPA
packages or simply for emacsspeak to load the Emacs's
lisp/emacs-lisp/eldoc.el file, then "you're golden", as they say.
