I hate to rewrite those steps more than 3 times. But I also know Emacs
contributors should not be forced to fix bug for me. Also I can't fix
this bug by myself. So I think it's not a bug, I can tolerate this
center line. Maybe I mastered skill for modify code in Emacs, I might
come back to fix this bug by myself. But now, let me close it. I'm not
hating anybody, just hate this process. Thanks for checking out.
