Subject: [PATCH] Fix window positions.

Graph and diff windows were swapped if user set `splitbelow` to 1:

    :set splitbelow    :set nosplitbelow

       +---+---+           +---+---+
       | D |   |           | G |   |
       +---+ S |           +---+ S |
       | G |   |           | D |   |
       +---+---+           +---+---+

     D - diff,  G - graph,  S - source

This commit fixes this -- now diff is displayed below graph regardless of
`splitbelow` setting.
