Thanks, it works for directories and files in Dired.

I have one question: how is it supposed to log/diff the root dir
from Dired?  When I put point on the root dir in the dired buffer,
`C-x v l' fails with:

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  expand-file-name(nil)
  vc-do-command("*vc-change-log*" 0 "rlog" ...)
  vc-rcs-print-log(... "*vc-change-log*" t)
  apply(vc-rcs-print-log (... "*vc-change-log*" t))
  vc-call-backend(RCS print-log (...) "*vc-change-log*" t)
  vc-print-log-internal(RCS (...) nil)
  vc-print-log()
  call-interactively(vc-print-log nil nil)
