+The arguments are:

+      a single thread. If nil this is read interactively from the minibuffer.
+  QUERY-CONTEXT: is an additional term for the query. The query used

+  TARGET: A message ID (with the id: prefix) that will be made
+      current if it appears in the pick results.
+  BUFFER-NAME: the name of the buffer to show the pick tree. If
+      it is nil \"*notmuch-pick\" followed by QUERY is used.
+  OPEN-TARGET: If TRUE open the target message in the message pane."
