spacemacs采用的是c++layer clang补全，其他配置没做改动。

descirbe-key：
’ runs the command self-insert-command (found in global-map), which is an interactive built-in function in ‘C source code’.
It is bound to many ordinary text characters.
(self-insert-command N)
Insert the character you type. Whichever character you type to run this command is inserted. The numeric prefix argument N says how many times to repeat the insertion. Before insertion, ‘expand-abbrev’ is executed if the inserted character does not have word syntax and the previous character in the buffer does. After insertion, ‘internal-auto-fill’ is called if ‘auto-fill-function’ is non-nil and if the ‘auto-fill-chars’ table has a non-nil value for the inserted character. At the end, it runs ‘post-self-insert-hook’.
似乎问题出在加粗的一段，但我不太懂elisp（基本语法了解）所以不会排查，能给点建议吗？
