Actually, everything that is stored in the file goes to the undo stack. 
I do not see how to avoid that.

Do other applications save change tracking status?

Would you find it good that, if you open a file for the explicit purpose 
of setting change tracking "on", then it will be necessary to fake 
another change for the purpose of being able to save it? Or that undoing 
all your changes may leave certain change unbeknownst to you?

There might be another way to avoid killing the redo stack. Do you know 
of any applicaiton that has a solution to this?
