vc: how to insert version number in buffer (vc-status is gone)

[Uwe Brauer <oub@mat.ucm.es>]

Hello

In ancient times, vc had a function called 
vc-status so it was possible to insert the vc version number into a
buffer with 

(defun my-vc-status-insert ()
  (interactive)
  (insert "Version")
  (insert (vc-status buffer-file-name))) 

This came in handy, if the modeline is gluttered and the file is large
so it is cumbersome to go at the beginning to the buffer in order to
check the version number. 

As I said vc-status is long gone so I would like to know how I could
insert the version number.

thanks
