Hi, Please find enclosed a small patch against emacs-lisp (packaged with 
emacs 26.3 on recent emacsen on recent ubuntu (20.4.0.2 ?)

I'd be more than happy to do the leg work to get it "install ready" but 
may need some advice on how to do that.

This patch works in live emacs after eval-region of the changes.

I have no idea who to contact on ubuntu side to get it accelerated in.

Thanks for reading. Please let me know if you need any additional 
reformatting etc...

Thank you
-Jason
