在Emacs中缩进C块注释

我正在尝试配置emacs以便很好地缩进我的C块注释.

Emacs(22.3)默认情况下(无论缩进样式如何):

/* My very long comment which spreads over multiple lines
* and thus needs to be filled.
*/

但我更喜欢的是:

/* My very long comment which spreads over multiple lines
 * and thus needs to be filled.
 */

我尝试使用c-offset-alist和语法符号"c",但它并没有帮助我理解这个问题:

(c-add-style "mine"
             '((c-basic-offset . 2)
               (c-block-comment-prefix . "* ")
               (c-offsets-alist
                (c . +)))
             )

有任何想法吗？提前致谢!

干杯,丹尼尔
