在 VIM 中格式化列表

Question

我想找到一种在 Vim 中轻松格式化列表的方法。
我检查了 PAR 和 Vim 的默认格式化程序。

pe

1. this is my text this is my text this is my text 
2. this is my text this is my text this is my text 
3. this is my text this is my text this is my text 
4. this is my text this is my text this is my text  

和

- this is my text this is my text this is my text 
- this is my text this is my text this is my text 
- this is my text this is my text this is my text 
- this is my text this is my text this is my text  

当我选择行并使用 PAR 和 VIM 将默认格式设置为 42 时，结果如下：

---

NUMBERED LIST

formatting with par:
参数错误：
(42) <= (0) + (50)

使用 vim 格式化：

1. this is my text this is my text this is
my text 
2. this is my text this is my text this is
my text 
3. this is my text this is my text this is
my text 
4. this is my text this is my text this is
   my text

带 '-' 的 LIST

使用 par 格式化：
过滤了 4 行（没有变化）

使用 vim 格式化：

- this is my text this is my text this is
  my text 
- this is my text this is my text this is
  my text 
- this is my text this is my text this is
  my text 
- this is my text this is my text this is
  my text

Vim does a better job formatting lists but it is not correct as well in a numbered list.
Par does have a lot of troubles formatting lists even when I use the prefix ("p") option like this:
'<,'>!par w42p4dh or '<,'>!par w42p3dh

有谁知道如何毫无问题地格式化列表的好方法？

尝试设置 fo+=n。来自 :help fo-table:

n       When formatting text, recognize numbered lists.  This actually uses
        the 'formatlistpat' option, thus any kind of list can be used.  The
        indent of the text after the number is used for the next line.  The
        default is to find a number, optionally followed by '.', ':', ')',
        ']' or '}'.  Note that 'autoindent' must be set too.  Doesn't work
        well together with "2".                    

        Example: 
                1. the first item
                   wraps 
                2. the second item
