Glad to hear you got a satisfactory setup.

Interesting idea of multiple keybindings for different completions.

If EUDC includes the other sources, do you foresee using just EUDC?  Or
do you think keeping the extra keys will give better usability?

What do you think the "out-of-the-box" behavior should be?  Should the
following:

    "emacs -Q"
    C-x m
    TAB

say "no completions found; to start adding contacts, do <something>".

Should the following:

    "emacs -Q"
    (in *scratch*) emacs-devel@gnu.org
    C-x m
    TAB

expand to emacs-devel@gnu.org via dabbrev-expand?

Pressing TAB in both those examples on Emacs 25.1 does nothing, and on
master inserts a literal TAB.

Thanks,
Thomas
