[gnu.emacs] Backups not done on C-x C-c

thakur%cfa201@HARVARD.HARVARD.EDU (Manavendra K. Thakur) (02/25/89)

Emacs will not create a backup file if you exit emacs by typing C-x
C-c (let's assume you type 'y' when emacs asks whether to save
modified buffers).  This is not always desirable.

Question: Is this a bug or a feature?  Is there a way to force emacs
to make backup files when exiting with C-x C-c ?

Also, as I understand it, Emacs will create a backup file (a 'twiddle
file') only the first time the file is saved each time the file is
visited.  How can I force emacs to create a backup file *everytime* I
type C-x C-s?

I'm new to hacking Emacs code, so any pointers would be greatly
appreciated.
