How can I Edebug in emacs --batch (also what to edebug?). I see that
enable-local-variables is `t' (default value), and still the
.dir-locals.el is ineffective in --batch. Otherwise, in regular emacs
sessions, the put safe-local-variable + .dir-locals.el combo works

Here's a minimal example.

1. Create a temp dir
2. Create the below setup-foo.el file in there.
3. touch
4. emacs --batch --eval '(load-file "setup-foo.el")' -f echo-foo

===== setup-foo.el =====
(defconst foo nil)
(put 'foo 'safe-local-variable 'stringp)

;; Uncomment below to make the .dir-locals.el set value to apply.
;; (setq enable-local-variables :all)

(defun echo-foo ()
  (message "enable-local-variables = %S" enable-local-variables)
  (if (boundp 'foo)
        (message "foo = %S" foo)
        (if foo
            (message "The value of `foo' from .dir-locals.el was applied.")
          (message "The value of `foo' from .dir-locals.el was *not*
    (message "`foo' is not defined")))
