bug#15322: VC log buffer scrolls itself

... perhaps I was going too far, but a fix is still needed to stop
point jumping to the beginning of the buffer when working-revision is
null (at least in Subversion). I suggest not calling
`goto-location-func' or setting vc-sentinel-movepoint when
working-revision is null, in `vc-print-log-internal'.

I also suggest a null working-revision be passed by
`vc-print-root-log', by the same argument Stefan used for
`vc-print-log'.
