Done. I took the liberty of pushing this additional change to the patch
I showed, which is essential to make this work.  I had forgotten to show
it.  Unless there are objections, we can close this bug.

 (defun display-buffer-assq-regexp (buffer-or-name alist action)
   "Retrieve ALIST entry corresponding to buffer specified by BUFFER-OR-NAME.
 This returns the cdr of the alist entry ALIST if the entry's
-key (its car) and BUFFER-OR-NAME satisfy `buffer-match-p', using
-the key as CONDITION argument of `buffer-match-p'.  ACTION should
-have the form of the action argument passed to `display-buffer'."
+key (its car) and the name of the buffer designated by
+BUFFER-OR-NAME satisfy `buffer-match-p', using the key as
+CONDITION argument of `buffer-match-p'.  ACTION should have the
+form of the action argument passed to `display-buffer'."
   (catch 'match
     (dolist (entry alist)
-      (when (buffer-match-p (car entry) buffer-or-name action)
+      (when (buffer-match-p (car entry) (if (stringp buffer-or-name)
+                                            buffer-or-name
+                                          (buffer-name buffer-or-name))
+                                          action)
         (throw 'match (cdr entry))))))
