在Vim中关闭分割窗口而不调整其他窗口的尺寸

Question

如果我打开一个Vim窗口，其中有2个分割（总共3个缓冲区可见），并且我调整了每个分割的视口，然后关闭一个缓冲区，另一个两个缓冲区的视口会自动调整大小。

当我关闭缓冲区时，是否有办法维持或至少更好地缩放分割？

1) Vim window with three splits, custom size: 
    +---+-------+---+ 
    | |  | | 
    | 1 | 2 | 3 | 
    | |  | | 
    +---+-------+---+ 
2) Close buffer 3, splits are resized to "best fit": 
    +-------+-------+ 
    |  |  | 
    | 1 | 2 | 
    |  |  | 
    +-------+-------+ 
3) I want it to stay like this, resize only adjacent buffer: 
    +---+-----------+ 
    | |   | 
    | 1 |  2  | 
    | |   | 
    +---+-----------+
