taglist and nerdtree

函数：function! s:Tlist_Window_Exit_Only_Window()中的winbunr(2)改为winbunr(3)，即只剩2个窗口时关闭，考虑到2个窗口肯定是同时存在，所以这样还是可行的：

 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(3) == -1

         bdelete

         quit

     endif

     else

     if winbufnr(3) == -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

同时在vimrc中需要设置：let Tlist_Exit_OnlyWindow=1
