Notmuch, Emacs and pinentry -- oh my

I only access the server with a terminal, and that's where Emacs is
running in. Curses is as graphical as it gets. ;-)

See https://www.gnu.org/software/emacs/news/NEWS.26.1, section "The
pinentry.el library has been removed.", remarks about minibuffer
vs. graphical pinentry programs.

I have tried 'epa-pinentry-mode' with both loopback and nil, and I tried
both with and without 'allow-emacs-pinentry' in gpg-agent.conf. It does
not seem to make a difference what I try, though.

As for the nuclear option of decoding on indexing: That worries me more
than using Emacs with some form of pinentry and gpg-agent.
