在我的quesiton中提到的 linum-off.el 已经解决了这个问题。说明在文件中：将文件放入Emacs加载路径，并将（require'linum-off）添加到〜/ .emacs。此脚本关闭仅指定模式的行号。我已经测试了，它工作正常。

linum-off.el mentioned in my quesiton has solved this. Instructions are in the file: place the file into the Emacs load-path and add (require 'linum-off) to ~/.emacs. This script turns off line numbering for the modes specified only. I've tested it and it works fine.
