No, this has nothing to do with oauth2---the automatic refreshing works
just fine. Its the auth-store that is asking for a password to read the
local plstore file (for some reason it caches the password for some
relatively short length of time, but then decides it needs the password
after a couple of hours).

Just to be really clear, all of the oauth2 stuff works automatically and
just fine (including for smtp for sending email).

Yes, I have been waiting for a good time to update my local emacs
repository so I can do a clean push. Not much time for emacs these
days.
