bar top/bottom border
Is there any way to put a bottom border on a bar positioned at the top of the screen?
I would like my bar and terminals to have the same background color.  I also like to keep hide_edge_borders both which means that the bar and adjacent terminals run together.  It would be nice to have the ability to separate them without using hide_edge_borders vertical (which adds a border on the bottom of the screen as well).  
Perhaps, something along the lines...
bar {
    position top
    color {
        border_bottom #rrggbb
    }
}
or
bar {
    position bottom
    color {
        border_top #rrggbb
    }
}
