我试图将vim中的columns变量设置为80.如果我在.vimrc中设置它，似乎没有变化。我在Ubuntu 14.04上使用gVim 7.4。
在我的cpp文件中，现有的长行不会更改为包裹在80列标记处。如果我开始键入一个新的长行，它将不会在80处换行。如果我在文件打开时设置列：set columns = 80，长行包裹在80列，但几秒钟之后，包装就会消失并且它就像我从未设置过列。
当我输入git commit消息时，columns变量可以正常工作。它只是在源文件中不起作用。
下面是我的.vimrc文件。那里有什么东西可以重置列吗？我试图禁用我的插件，但这似乎没有帮助。

'columns'选项是屏幕的列数（物理大小），通常由终端设置。您想要的是'textwidth'要插入的文本的最大宽度。
常见的错误是在'textwidth'文件中设置'shiftwidth'或~/.vimrc等缓冲区本地选项。最好按文件类型设置这些，并在设置这些选项时使用setlocal。通过以下方式获取缓冲区的文件类型：:set filetype?
E.g。假设文件类型为javascript，则将以下内容添加到~/.vim/after/ftplugins/javascript.vim：
setlocal textwidth = 78
