Bah, sorry! I forgot that this was a two-part fix, and I only gave you
one of the parts. The other part is in:

https://git.sr.ht/~girzel/EBDB/commit/046750093275092db4c2407b22482d6d0d702453

But don't worry about it, I'm 99.9% sure that this problem is taken care
of. Sorry to make you test in vain.

This is a bigger problem -- I'm committed to supporting Emacs 25. I
think I'll just write my own function (read: copy and paste Org's) to do
the same thing.

Thanks,
