From: Aneesh Kumar K.V <aneesh.kumar at gmail.com>

This patch helps in customizing search result display
similar to mutt's index_format. The customization is done
by defining an alist as below

(setq notmuch-search-result-format '(("date" . "%s ")
				     ("authors" . "%-40s ")
				     ("subject" . "%s ")
				     ("tags" . "(%s)")))

The supported keywords are date, count, authors, subject and tags.
