good idea!

have incorporated that in the appended patch.
also, the 'when' part should only include the actual deletion of 
the backup file
>  	(ignore-errors
>  	  (delete-file auto-save-file-name))
rather than also draft diassociation
>  	(let ((message-draft-article draft-article))
>  	  (message-disassociate-draft)))
also fixed in the updated patch.
