Subject: [PATCH] Support function values in notmuch-saved-searches so that
	searches can be generated dynamically
Date: Fri, 19 Nov 2010 19:42:49 +0100

Precedence: list

This permits saved searches like "today".

This is similar functionality to David's patch, but uses an accessor so that queries are always evaluated dynamically.
