Powerline separators

[Shourai]

This theme does not play nice with powerline separators.
See the following pictures:

The separator does not align with the complete height of the mode-line.
To mitigate this I had to set underline and overline to nil
and set the color of the :box to the (back|fore)ground value.

To override these values one could put the following in their config file:

    (custom-set-faces
    '(mode-line ((t
    (:underline nil :overline nil :box
                (:line-width 1 :color "#fdf6e3")
                :foreground "#fdf6e3" :background "#657b83")))))

Change the color of the line-width according to your specific case.

Is this something that could be considered a bug?
