You are correct.  It was 0.  If I change to 1 it will only delete 
the backup file if auto-save happens first.  IOW if the auto-save 
file exists and I make a change to my file (without recovering) and 
save the change before an auto-save happens then the obsolete 
auto-save file is not purged.  If I wait for an auto-save before 
saving manually then the auto-save file is cleaned up.

Now that you point it out ... this is true.  But I think that having
auto-save ON by default is quite a good thing.
