Vim评论在行尾的延续

Question

所以,假设我有一大堆代码

int i = 0; // Do some junk here<cursor is here>

if(i == 0){
  blahblahblahblah;
}

blahblahblah;

是否有可能告诉vim当我按Enter键时,我想要它会导致以下结果:

int i = 0; // Do some junk here
           // <cursor is here>

if(i == 0){
  blahblahblahblah;
}

blahblahblah;

我知道它会为一个单独排队的评论做到这一点,但我无法弄清楚这一点.

我不\xe2\x80\x99t 知道是否有一个插件（但可能有一个），但是以下映射应该可以通过按 Enter 键添加一行（尽管有更多方法来添加行） ）：

\n\n
