NOW I suppose I AM dealing with a dead horse.  But in hopes of helping and at
the risk of being told once more to f___ off, let me try once more:

+(defun read-regexp-defaults ()
+  (if (not read-regexp-user-defaults) t
+    (let ((user-default (assoc this-command read-regexp-user-defaults)))
+      (pcase user-default
+         (`(,cmd ,(and (pred functionp) getter))
+          (funcall getter))
+         (`nil nil)
+         (_ t)))))

Don't you think that that will return nil when `this-command' =
`exit-minibuffer', since `exit-minibuffer' is not in your value of alist

And if it returns nil, don't you think that the following will then print `cmd:
exit-minibuffer defaults: nil'?

+  (let ((user-defaults (read-regexp-defaults)))
+    (unless (eq user-defaults t)
+      (setq defaults user-defaults)
+      (message "cmd: %s defaults: %S" this-command defaults)))

If this doesn't help, I give up and lie down next to your dead horse.
