I switched the key-binding of C-M-i to call `completion-at-point'
directly, and the Org-specific completion still worked just fine, so
that's something!

I notice that `ispell-complete-word' has a FIXME about
`completion-at-point-functions', so I assume it doesn't currently work
with capf. But it's nice to know that someone (Stefan Monnier,
naturally) wishes it would (or he did back in 2012, when he added that
comment).

I do know about hippie expand, but it seems like a repeat of the same
problem: another mini-framework that can draw completions from multiple
sources. It feels like capf is going to be that framework in the future,
so I'd like to try hard to stick to that, if possible.
