How to set mode line to show full path of current file

[Ashwin Purohit]

Hi all,

I'd like to set the mode line to show the full path of the current file, but only to _replace_ the filename with the fullpath, instead of wiping the entire mode line and replacing it by just the filepath. There are other things, like line position and time that I would like to keep on the mode line.

What I'm currently using:
;; set mode line to show full path of current file                                                                                                                                                                                                                            
(setq-default mode-line-format
   (list '((buffer-file-name " %f"
              (dired-directory
               dired-directory
                (revert-buffer-function " %b"
               ("%b - Dir:  " default-directory)))))))

Thanks!
