bug#15322: VC log buffer scrolls itself

And I think that makes sense.  It's natural to select a particular
revision when running vc-print-log from (say) vc-annotate, but for
a plain `C-x v l', the user just wants to see "the log" and presumably
doesn't care about which revision happens to be current.

IOW, I think we're trying too hard here.
