Hello, Emacs.

Right after posting the original post, I tried going back to the
previous version of gnupg, namely gnupg-2.2.41.  All tests then worked
on master, with no hangs.

The version which doesn't work well together with Emacs is
gnupg-2.2.42-r2.  (I've a feeling that the "-r2" there is a purely
Gentoo label).

So it seems that some interface to gnupg has changed, possibly
unintentionally.

I don't know this part of Emacs at all well, that is gnupg and
sub-processes, so would anybody help me on sorting out what's going
wrong, here?  Thanks!
