IIRC those used to *have* to be set, and that was done via the
loginmanager (e.g. gdm), but that doesn't seem to be necessary any
longer, but I guess mutt depends on them being there in order to find
out that gpg-agent is running.  Is that correct?

Anyway, making the changes you propose makes mutt behave the way I
want.  Thanks!

Code as if whoever maintains your program is a violent psychopath who knows
where you live.
