And while we are at it this one also can be simpler:

-	(let ((plain-addrs (mapcar 'car recipients))
-	      subaddrs recip)
-	  (while plain-addrs
-	    (setq subaddrs (assoc (car plain-addrs)
-				  message-hierarchical-addresses)
-		  plain-addrs (cdr plain-addrs))
-	    (when subaddrs
-	      (setq subaddrs (cdr subaddrs))
-	      (while subaddrs
-		(setq recip (assoc (car subaddrs) recipients)
-		      subaddrs (cdr subaddrs))
-		(if recip
-		    (setq recipients (delq recip recipients))))))))
+        (setq recipients
+              (loop for (r . a) in recipients
+                    for assoc = (cdr (assoc r message-hierarchical-addresses))
+                    when assoc append assoc into recip
+                    unless (member r recip) collect (cons r a) into results
+                    finally return (cdr results))))
