Patches 1-3 look fine +1.

This one I am less sure about. I agree with the principle but for my use
case it is a little annoying:

I only use one name for all my addresses (Mark Walters), some addresses
are mark@.. and some walters@..

ido-completing-read is definitely less nice to use when all the addresses
match mark and walters.

I wonder if we could get the old behaviour in a more robust fashion. Two
possibilities we could consider are

1) if getting the information from the config file (when there is
necessarily a single name) then only complete the addresses.

2) make notmuch-identities a list of cons cells (name . email). Then
there is no parsing and the old method could be robust.

OTOH I can get used to the change.

Best wishes

Mark
