爲什麼vim無法識別非空白字符後的註釋？這怎麼解決？

Question

vim可以識別開始行的註釋或僅跟隨空格字符，如下面的那些字符。

// This is recognized as a comment by vim. 
// Pressing <Enter> continues the comment on the next line. 
{ 
    // vim will also automatically format these comments if they exceed textwidth 
    // characters in length. 
} 

但是，當註釋跟在代碼後面時，vim似乎無法識別它，以便在下面一行中添加註釋引線。

DoSomething(); // vim does not recognize this as a comment 
and will neither continue the comment after <Enter> is pressed nor break automatically if the line exceeds textwidth characters. 

如果有幫助，我的這是我的〜.vimrc文件。我通常:set cindent，但它似乎對評論沒有影響。

set cino=L0,l1,g1,h1,N-s,t0,(0,w1,W2s 
set expandtab 
set formatoptions=croq 
set shiftwidth=2 
set tabstop=2 
set textwidth=80 

謝謝！

評論與// begining有效到只有結束的行。
