Draw left bars even when there is no left pane.

If there is no left pane, but the middle pane is not showing the
beginning of the line (vs2pos is not zero), we need to show the
bars to indicate that that is not the start of the line.
Otherwise the middle pane looks deceptively as if it were the left
pane.

In the (vs2pos == 0) case, it doesn't matter; the middle pane
shows a prefix, and so is semantically similar to the left pane.
