~/.viminfo权限引起的vim无法记住上次编辑的位置（附vim配置文件）

现象：

已经在～/.vimrc中增加了下面一行：

au BufReadPost * if line("'\"") > 0|if line("'\"") <= line("$")|exe("norm '\"")|else|exe "norm $"|endif|endif

但是只有用sudo vim的时候才会记住上次编辑的位置，直接vim总是从第一行开始。

原因：

[yuanlulu@ubuntu: ~]$ll ./.viminfo

-rw------- 1 root root 4558 2011-12-09 13:58 ./.viminfo

原来记录位置的文件仅仅对root开放了读写权限。

解决办法：

对非root用户增加对~/.viminfo的读写权限

sudo chmod a+w ./.viminfo

sudo chmod a+R ./.viminfo

附上自己的vim配置文件
