columnar faces in search results

[David Edmondson]

Does anyone modify any of the following faces to control the display of
search results?

	notmuch-search-date
	notmuch-search-count
	notmuch-search-subject
	notmuch-search-matching-authors
	notmuch-search-non-matching-authors

(i.e. to get something like
http://notmuchmail.org/screenshots/Screenshot-notmuch-search-fruitsalad.png.)

I'm looking at how the priority layering of faces in the search results
works, and these add significant complications...
