Subject: [notmuch] [PATCH 2/2] notmuch-show: add optional argument for query
	context instead of using global binding notmuch-search-query-string
Precedence: list

From: David Bremner <bremner@unb.ca>

Also modify the one call to notmuch-show in notmuch.el.  This makes
the call (notmuch-show thread-id) will work when there is no binding
for notmuch-search-query-string; e.g. when called from user code
outside notmuch.
