Adding Undo

[timsofteng]

Hello. I see in readme that undo is not support after saving.
Is it any way to implement it?
I find this plugin good which is different of course but it supports undo:

maybe it can help

I use a regex replace from sed to replace text that not belong to vim.
Of course it has a way to do that but it's too complicated now.. PR is welcome.

@windwp, How about always create backup option in setup? Then user can choose to delete or restore it.
