我是一个新的 vim 用户。在问这个问题之前，我已经了解了 SO 提出的一些类似问题，例如： Q-1、Q-2、Q-3和Q-4。他们都没有解决我看似简单的问题。如果有人可以帮助我了解我在这里缺少的东西，那就太好了。
问题描述：我正在使用 Ubuntu-12.04 32 位系统。无论我在~/.vimrc文件中进行什么更改，它都不会反映在 vim 显示我的文件的方式中。最近，我添加了几行来将状态行更改为vim更具信息性和颜色编码的内容（从此处复制）。即使在采购~/.vimrcusing之后:so ~/.vimrc，也没有实现任何预期的更改，并且状态行保持与默认值相同。下面给出的是我的~/.vimrc文件。
请帮助我了解我缺少什么？为 Statusline 添加的行位于~/.vimrc文件末尾。
谢谢
我的~/.vimrc文件：
" All system-wide defaults are set in $VIMRUNTIME/debian.vim (usually just
" /usr/share/vim/vimcurrent/debian.vim) and sourced by the call to :runtime
" you can find below. If you wish to change any of those settings, you should
" do it in this file (/etc/vim/vimrc), since debian.vim will be overwritten
" everytime an upgrade of the vim packages is performed. It is recommended to
" make changes after sourcing debian.vim since it alters the value of the
" 'compatible' option.
" This line should not be removed as it ensures that various options are
" properly set to work with the Vim-related packages available in Debian.
