Have done as instructed

(defun vodil-bfnwidth (width)
  (setq mode-line-buffer-identification
        (propertized-buffer-identification (format "%%%db" width))))

(defvar vodil-deploy-bfname nil "")

(unless vodil-deploy-bfname
  (vodil-bfnwidth 5))

  (setq-default mode-line-format
    '( "%e"
            (:eval (if vodil-deploy-bfname
                        vodil-panelit-bfname
                     mode-line-buffer-identification)))) )

Still, I cannot see any difference in the buffer name width.
