delete-auto-save-files

[Uday S Reddy]

The doc-string for delete-auto-save-files says:

   *Non-nil means delete auto-save file when a buffer is saved or 
killed.

   Note that auto-save file will not be deleted if the buffer is killed
   when it has unsaved changes.

I can't quite understand the "note that..." bit.  It directly 
contradicts the first
sentence.  The behaviour of all versions of Emacs I have used is to 
delete the
auto-save file when a buffer is explicitly killed (assuming this 
variable is set to non-nil).  The Emacs Lisp manual doesn't say anything 
corresponding to the second sentence either.

Is this a bug in the doc-string?
