For consistency with ‘C-x v L’ (‘vc-print-root-log’) whose
prefix argument is described in the longer description
in (info "(emacs) VC Change Log")

But since you asked I looked closer and see that e.g. a prefix argument
of ‘C-x v =’ is described in the short summary in the same node
(info "(emacs) Old Revisions")

  ‘C-x v =’
       Compare the work files in the current VC fileset with the versions
       you started from (‘vc-diff’).  With a prefix argument, prompt for
       two revisions of the current VC fileset and compare them.

So I installed something better.
