bug#6870: Make vc-root-diff work in more modes

   It makes sense to me that vc-root-diff uses "(vc-responsible-backend
default-directory)" when in a dired-mode buffer.  But since vc-root-diff
is not at all about the current buffer, why not also make that the
default for shell-mode, diff-mode, or any of the other modes for
non-version-controlled buffers that may be generated in a working copy?
