1.5. I looked around in that file and didn’t see elisp-eldoc-funcall
defined anywhere (neither can I in the old eldoc.el that comes with
Emacs 27).

Thanks for reporting this.  I introduced this bug.  The function you get
the error for is not defined in eldoc.el ? 1.5.0 but referenced there:

Actually, a similar bug was lurking before I touched the function, I
just exposed it by making ElDoc available on GNU Elpa.  I think the
patch below is the easiest way to fix it, along with bumping the ElDoc
version to 1.8.  Works in my tests of Emacs 27 and Emacs 26.  Can you
try it out?
