gvim的一个问题

食古不化

把/etc/vim/vimrc中的那几行：

1. " In text files, limit the width of text to 78 characters, but be careful
2.   " that we don't override the user's setting.
3. "  autocmd BufNewFile,BufRead *.txt
4. "        \ if &tw == 0 && ! exists("g:leave_my_textwidth_alone") |
5. "        \     setlocal textwidth=78 |
6. "        \ endif

复制代码

彻底注释掉！！
里面还说we don't override the user's setting？？

哪位给看看这个判断语句写的什么意思！！

我想，其意图之一是：若您对/etc/vim/vimrc无修改权限，则可以通过在自己的用户配置文件里定义一个g:leave_my_textwidth_alone变量，来阻止/etc/vim/vimrc 对 textwidth 选项的修改。
