.vimrc textwidth 不适用

Question

以下是我的 .vimrc 文件的全部内容：

出于某种原因，set wrap和set textwidth=73（在文件底部）不起作用（我想让文件在 73 列处换行）。我仍然可以进入一个文件并输入超过 73 列。

这里是否有需要修复的冲突命令？还是我做错了什么？

set expandtab                   " tabs are spaces, not tabs

set matchpairs+=<:>

set foldmethod=syntax  "fold based on indent
set foldnestmax=10      "deepest fold is 10 levels
set foldlevel=0         "this is just what i use
set wrap
set textwidth=73
set formatoptions+=t

编辑：我希望 VIM 自动换行 73 行（实时）。那可能吗？我试过添加set formatoptions+=t换行文本，但它仍然无效。

也许不是最好的解决方案，但尝试在自动命令中分配textwidth和formatoptions，然后格式化文件的所有行。

autocmd BufRead * set fo+=t tw=73|normal gggqG

这在我的测试中有效。您可以更具体，并*用*.txt或类似替换。
