Using modeline to fold vimrc in chapter 22

[CyrusYip]

This single line sets foldmethod to marker. I think this method is better than autocmd method, because filetype checking is not needed, and it only affects 1 file(vimrc), not affecting other vim files.

" vim:foldmethod=marker

Note: this line should be placed within 5 lines of the top or bottom of vimrc file.
