How can I prevent the history being lost?
Huh?
When I save a file, undo levels are kept. Using u then undoes, but marks the
file as modified. Using Ctrl-R redoes, and the 'modified' flag will disappear
when the file-in-memory is identical to the file-on-disk.
The undo history is only lost when I close Vim with :qa
