.vimrc配置（持续更新）

参考vimbook-OPL，windows下默认配置和网友的总结，感觉自己也要维护配置文件才算入门。

文件目录
unix/linux: $HOME/.vimrc
windows: $vim安装目录_vimrc

这些都可以在gvim的【启动设置】中打开

gvim和vim的区别就是前者是GUI，后者是在控制台环境中的（Linux下叫xterm，注意如果xterm本身带配色的话，它会影响.vimrc的配色）

最后附上本文重点

网友提到的 set lines=999 columns=999 亲测在Ubuntu 18.04.02中会报错

The program ‘gvim’ received an X Window System error.
This probably reflects a bug in the program.
The error was ‘BadAlloc (insufficient resources for operation)’.
(Details: serial 275 error_code 11 request_code 53 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
E852: The child process failed to start the GUI
请按 ENTER 或其它命令继续

所以我改小了。
