将系统范围的特定于语言的Vim ftplugin .vim文件放在何处

我在中放置了一些与语言无关的基准设置/etc/vimrc，这些基准设置是用户的默认设置，除非用户覆盖它们。

在系统范围内，存放各个{language}.vim文件的规范位置在哪里？

基于每个用户，我总是将它们放在中~/.vim/ftplugin/{language}.vim，即~/.vim/ftplugin/python.vim可能包含：

setlocal colorcolumn=72,80

但是，这仅适用于给定的用户。

系统范围的版本应该放在哪里~/.vim/ftplugin/？我应该直接编辑/usr/share/vim/vim74/ftplugin/python.vim还是在其他地方覆盖它？
