A similar bug happens with another utility of mine, editing stuff in a 
dired-buffer. Below an example-version:

---

(defun foo ()
  (interactive "*")
    (wdired-change-to-wdired-mode)
    ;; Do some edits
    (wdired-finish-edit))

---

M-x byte-compile-file RET complains

---

In end of data:
eil.el:5:6: Warning: the function ‘wdired-finish-edit’ is not known to be
    defined.
---

Which isn't useful, as (wdired-change-to-wdired-mode) already loaded wdired.
