What I meant was that I don't see any way of inserting EBDB completion
results into an arbitrary list of other results coming from other user
configuration. If we set `message-expand-name-standard-ui' non-nil then
we get to use the `message--name-table' function, but that function only
consults BBDB, EUDC, and ecomplete. 

I guess I was expecting some sort of setup that uses
`completion-table-merge' on an option holding a bunch of functions. I'd
just provide a EBDB function to be added to that option, and we're done.

All this code makes my eyes cross, though, so I wouldn't be surprised if
I'm missing the right point of injection.

Thanks,
