在Vim中关闭分割窗口而不调整其他窗口的大小

如果我打开一个带有2个分割的Vim窗口(3个总缓冲区可见)并且我调整了每个分割的视口，那么我关闭一个缓冲区，另外两个缓冲区的视口会自动调整大小。

当我关闭缓冲区时，有没有办法维持或至少更好地扩展分割？

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     |
  |   |           |
  +---+-----------+

set noea
" i.e.
set equalalways

请参阅Vim文档中的equalalways。
