The next steps are are just one insert:
1. Insert 1.
2. Now <C-R>=setline('.','12')<CR>
3. Insert <CR>
4. Exit insert mode and undo (u).

The buffer should be empty but it has two lines, the first one is empty and the second one has the number 2 in it. Since the buffer isn't empty, I should get E37 when I :quit, instead vim exits without any message.

Let's see if that works.

Thanks,
