    SpaceDrawer: cairo_stroke() each character
    
    draw_nbsp_at_pos() already called cairo_fill() or cairo_stroke(). In
    case of cairo_fill() (for a narrowed nbsp), it affected the previous
    char. So now, cairo_stroke() is called for each character, so that
    drawing a character doesn't affect the drawing of another.
    
    There is a screenshot of the bug at:
