I figured out previous question now, it's because ~expand-file-name~ on ~nil~.

    #+begin_example
    Debugger entered--Lisp error: (wrong-type-argument stringp nil)
      expand-file-name(nil)
      (file-name-as-directory (expand-file-name dir))
      (let ((mkdirp (cdr (assq :mkdirp params))) (fnd (file-name-as-directory (expand-file-name dir)))) (if (and (string= mkdirp "yes") fnd) (make-directory fnd 'parents)) (or (and dir (file-name-as-directory (expand-file-name dir))) default-directory))'
    #+end_example

After fix, the patch works fine and passed all tests include my write corresponding test.
