argument error when cursor on line with no filename

[chipschap]

An argument error appears when in peep-dired and the cursor is (mis)positioned to a line that has no filename (such as the top of the directory buffer). This fixes it:

(defun peep-dired-display-file-other-window ()
  (let ((entry-name (dired-file-name-at-point)))
;; Patch for mispositioning (next 2 lines)
    (unless (or (not entry-name)
	     (member (file-name-extension entry-name)
                        peep-dired-ignored-extensions)
                (> (nth 7 (file-attributes entry-name))
                   peep-dired-max-size))
etc.
