Sorry for doing this so piecemeal, but I'd like to revise the jump
to the end, too:

Since this doesn't account for the current position in the queue,
it is really an upper bound.  log_scroll_down(view, INT_MAX) would
do the same.  While traversing the queue is not a problem in practice,
it is inelegant.

> +		s->selected = MIN(view->nlines - 2, s->commits.ncommits - 1);

> +		break;
> +	}

I would like to copy the approach from the tree and ref views:
Start at the tail and traverse backwards as far as required.
OK?
