  Ok that the form I know. backend is required.

  In fact it does not work. vc-checkin launches a very
  complicated process of interaction opening the log buffer to
  setup the check in message. In fact if you do not want this
  process to run interactively vc-checkin is maybe not the
  right method. You might replace your code by :

  (vc-call-backend 'RCS 'checkin (list (buffer-file-name)) "")

  Sure it won't accomplish certain tasks around check in
  performed by vc-checkin but if yuou only want to check in
  ....
