所以我打开VIM：
$ vim
然后我打开 3 个文件：
:e file1.txt
:e file2.txt
:e file3.txt
正如预期的那样，有 3 个缓冲区，但它们的编号如下：
- 1：文件1.txt
- 2：文件2.txt
- 4：文件4.txt
有任何想法吗？
$ vim --version

和：
$ cat ~/.vimrc
syntax on
set number
set mouse=a
call pathogen#infect()
filetype plugin indent on
在 VIM 上：
:ls!
1 "file1.txt" line 1
2 # "file2.txt" line 1
3u a- "-MiniBufExplorer-" line 0
4 %a "file3.txt" line 1
Press ENTER or type command to continue
原因：这个“问题”是由于 MiniBufExplorer 在:e file2.txt.
当 vim 启动时 MiniBufExplorer 没有打开，当 I 时也没有:e file1.txt。但显然，当打开 2 个或更多文件时，它会自动打开，占用下一个缓冲区（因此占用缓冲区 3）。
解决方案：使用不会用完缓冲区的其他插件。
