The problem is that the argument of this function should be a buffer,
not a window as in 'shrink-window-if-larger-than-buffer'.
This is why bug#52855 proposed to add a new function

  shrink-buffer-if-larger-than-buffer

But not sure if this should be added to window.el,
or better to leave in vc.el with the name vc-shrink-buffer?
