+I can definitely do that. But as a comparison\r
+notmuch-search-get-result and notmuch-search-find-thread-id "work" in\r
+any buffer in the sense of returning nil but not complaining so perhaps\r
+the current version is more consistent. \r
+\r
+Plausibly a comment and an explicit nil case would be clearer for the other modes.\r
