  I meant the operation after I skimmed the new options.  Suppose I
did what you suggested.  Now I run make oldconfig in order to actually
create a new config, based on a current one.  And that is taking me 
more time then I thought it would.  So I want to manually save what
I did so far.  Perhaps there is an unexpected shutdown within 5 
minutes. Or I have to spend some time on other issues. Or whatever.
How would I save my current work?
If you'll remember that most editors (automatically) create backups
for the current work every 1 hour, or so, you might better understand
what I meant.
