Note that you can give the notmuch address --output option multiple
times to control the output. For example,

~$ notmuch address --output=sender --output=recipients id:878tdy8a2q.fsf@ligo.caltech.edu
Jameson Graef Rollins <jrollins@finestructure.net>
Daniel Kahn Gillmor <dkg@fifthhorseman.net>
Jani Nikula <jani@nikula.org>
notmuch@notmuchmail.org

~$ notmuch address --output=recipients --output=address id:878tdy8a2q.fsf@ligo.caltech.edu
dkg@fifthhorseman.net
jani@nikula.org
notmuch@notmuchmail.org

~$ notmuch address --output=sender --output=recipients --output=address --output=count id:878tdy8a2q.fsf@ligo.caltech.edu
1	notmuch@notmuchmail.org
1	jrollins@finestructure.net
1	dkg@fifthhorseman.net
1	jani@nikula.org

I prefer this to separate options.

notmuch search uses separate --entire-thread, --body, and --include-html
options, and I think those are getting messy.
