Vim：让 gq 不要在注释块中替换"**"

假设我有一个不错的注释块，比如下面的那个

/*
** This is a nice comment block. Displace the `**'s and I will eat your nose! Also, here is a long line of text clearly longer than the textwidth, which should force gq to rearrange the lines. Wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee...
**
**
*/

并且我应用CCD_ 1来格式化它，并确保没有一行超过字符计数。如何使gq不替换每个注释行前的首字母"**"？

非常感谢！
