from gpg(1):

              Make  sure that the TTY (terminal) is never used for any output.
              This option is needed in  some  cases  because  GnuPG  sometimes
              prints warnings to the TTY even if --batch is used.

So i think that --batch does not imply --no-tty.

Why GnuPG might insist on causing an error if it has no tty in those
cases, i can't really justify, but there it is.

This is one part of a two-part bug, both of which i bear some
responsibility for.  The other part is the aforementioned
https://bugs.debian.org/913614, the fix for which is already in both
testing and stretch-proposed-updates.  Luckily, if *either* GnuPG or
notmuch-emacs is fixed, the problem goes away.  But both fixes are in
principle the right thing to do, so please queue this for the notmuch
mainline at least.

i don't think there's any urgency here from a debian perspective, since
we're unlikely to get anything fixed before the next point release
anyway, and the other leg of the bug is already solved in the next point

If there are other cleanups you're thinking about trying to get into
debian stretch's next point release, by all means fold this one in,

Other operating systems or vendors might want to include this patch if
they're running some version of GnuPG that makes the same mistakes as
https://bugs.debian.org/913614, however.
