如何让vim用正确的缩进格式化项目符号列表

在 vim中,我可以设置textwidth选项,然后将新文本格式化为wrap.我也可以使用“gq”命令来显式包装文本.但是,使用项目符号列表的行为对我来说有点意外. vim文档讨论了使用带有连字符的项目符号的项目符号列表.当我尝试这样做时,它开始没问题：

- This is a bulleted list item that
  has been wrapped. It looks good.

但是,如果我继续第三行,它会放弃缩进：

- This is a bulleted list item that
  has been wrapped over more than
two lines. The indentation for lines
after the second is unexpected.

这发生在：

formatoptions=tcq
comments=s1:/*,mb:*,ex:*/,://,b:#,:%,:XCOMM,n:>,fb:-

为了清楚起见,我想要这样的缩进：

- This is a bulleted list item that
  has been wrapped over more than
  two lines. I want every line after
  the first to get the same indent.

经过进一步调查,看起来我只需要“设置自动注册”来获得预期的行为.这似乎适用于文本包装和键入“gq”命令.
