我们知道（不知道也没事）Taglist插件有自动退出功能，即只剩下一个文件的时候，即使Taglist窗口开着，在主窗口用:q的时候会同时退出Taglist窗口，而Nerd_Tree默认并没有这个功能，我们可以仿照Taglist插件来给Nerd_Tree插件天上这个功能。

首先插入如下代码

" Exit Vim itself if only the taglist window is present (optional)
let s:NERDTreeBufName = 'NERD_tree_'
	augroup Exit_onlywindow
		"当进入Nerd_Tree的buffer时也检测是否需要退出
		exec "autocmd BufEnter ". s:NERDTreeBufName .
		\"* call :Tlist_Window_Exit_Only_Window()"
		autocmd BufEnter __Tag_List__ nested
		\ call s:Tlist_Window_Exit_Only_Window()
	augroup end

然后把Tlist_Window_Exit_Only_Window的函数拷贝进去

" Tlist_Window_Exit_Only_Window
" If the 'Tlist_Exit_OnlyWindow' option is set, then exit Vim if only the
" taglist window is present.
function! s:Tlist_Window_Exit_Only_Window()
    " Before quitting Vim, delete the taglist buffer so that
    " the '0 mark is correctly set to the previous buffer.
    if v:version < 700
	if winbufnr(2) == -1
	    bdelete
	    quit
	endif
    else
	if winbufnr(2) == -1
	    if tabpagenr('$') == 1
		" Only one tag page is present
		bdelete
		quit
	    else
		" More than one tab page is present. Close only the current
		" tab page
		close
	    endif
	endif
    endif
endfunction

OK了，看看效果吧
