vim记忆上次浏览文件的位置

在windows下用gvim，这个选项是默认打开的。

也就是用vim打开文件时，可以记忆退出时的位置，从而再次打开就会直接跳到上次的位置。

该项控制命令写在$VIMRUNTIME/vimrc_example.vim下，可以把下面的命令拷贝到 .vimrc文件中，本方法尤其适用于Linux用户：

" Only do this part when compiled with support for autocommands.
if has("autocmd")

" Enable file type detection.
" Use the default filetype settings, so that mail gets 'tw' set to 72,
" 'cindent' is on in C files, etc.
" Also load indent files, to automatically do language-dependent indenting.
filetype plugin indent on

" Put these in an autocmd group, so that we can delete them easily.
augroup vimrcEx
au!

" For all text files set 'textwidth' to 78 characters.
autocmd FileType text setlocal textwidth=78

" When editing a file, always jump to the last known cursor position.
" Don't do it when the position is invalid or when inside an event handler
" (happens when dropping a file on gvim).
" Also don't do it when the mark is in the first line, that is the default
" position when opening a file.
autocmd BufReadPost *
    \ if line("'\"") > 1 && line("'\"") <= line("$") |
    \   exe "normal! g`\"" |
    \ endif

augroup END

else

set autoindent   " always set autoindenting on

endif " has("autocmd")
