minimally these two assignments to list->iterator should be right next
to each other, with a comment explaining what the heck. But I think the
following is more idiomatic

-	/* force copying onto the heap */
-	list->iterator = new Xapian::TermIterator;
-	*list->iterator = notmuch->xapian_db->metadata_keys_begin (CONFIG_PREFIX + (prefix ? prefix : ""));
+	list->iterator = new Xapian::TermIterator(notmuch->xapian_db->metadata_keys_begin
+						  (CONFIG_PREFIX + (prefix ? prefix : "")));

so that's what I've done in git
