FWIW, on my system I see that warning with all the vc-*.el files that
call vc-run-delayed.  The only exception is vc-svn.el, and the reason
is this single line:

  (autoload 'vc-expand-dirs "vc")

If you remove it, the warning will appear in vc-svn.el as well.
(Loading vc loads vc-dispatcher as a side effect.)

Another data point: replace this:

  (eval-when-compile (require 'vc))

with this:

  (require 'vc)

and the warning also goes way.  So evidently there's some difference
between these two, or maybe a byte-compiler bug.
