Re: Next XOAUTH2 patch: nnimap-login

[Cesar Crusius]

Let me reply to my own question:

Better not to do anything: not only the smtpmail patch is probably a year away
from deployment, but there are changes in auth-pass in Emacs 26 that
make dealing with all the possible combinations awkward.

What I'm going to do is to get the auth-source-xoauth2 package ready and
working, at this point, strictly through advises, and using the MELPA
auth-password-store package instead of the one included in Emacs
26.

Once things settle down we can talk more patches.
