This patch works fine on new buffer or existing file(one line) editing.
However, This patch seems incomplete when existing file(two or more lines)
editing.
How to reproduce.
1.
$ echo -e "\n" > foo
$ od -t x1c foo
0000000 0a 0a
\n \n
0000002
$ vim -N -u NONE --noplugin foo
2. input below.
ia<Esc>o1<Esc>a2<C-R>=setline('.','1234')<CR><CR><Esc>
3. Contents of the buffer
--------
a
120
34
--------
4. undo (first time)
--------
a
12
34
--------
5. undo (second time)
--------
a
1 <=== ?
34
--------
6. undo (third time)
--------
a
34 <--- ??
--------
