    build-log: don't muck with insert/selection mark
    
    We want to just scroll to the bottom, without touching the insert/selcetion
    mark. "move-cursor" does this just fine.
    
    We still need to deal with the problem of where the user has manually
    scrolled up, and not continue to autoscroll.
