Here's an initial attempt:

(defun vc-mode (&optional arg)
  "*Toggle VC (Version Control) mode.
With prefix ARG, turn VC mode on if and only if ARG is positive.

`C-x v' is the prefix key for the following commands:
\\{vc-prefix-map}"
  (interactive "P")
  (if (or (and (null arg) (not vc-mode)) ; toggle on
          (> (prefix-numeric-value arg) 0)) ; turn on
      ;; Turn VC on:
      (if buffer-file-name
          (if (file-exists-p buffer-file-name)
              (vc-find-file-hook)
            (vc-file-not-found-hook))
        (setq vc-mode " VC"))
    ;; Turn VC off:
    (progn
      (if buffer-file-name
          (vc-file-clearprops buffer-file-name))
      (setq vc-mode nil))))
