[António Fernandes <antoniof src gnome org>]

commit bf253462a055082ba5c7839ebf1318abf6c4e66d
Author: António Fernandes <antoniof gnome org>

    pathbar: Refine style
    
    Get closer to mockups by not showing a separator before the menu button.
    
    Instead, a border is added only upon scroll underflow.
