	`bookmark-write-file': use `write-file', not `write-region', to get
	backups
Date: Mon, 24 Sep 2012 11:41:39 -0700

I believe that `bookmark-write-file' should use `write-file', not
`write-region', because otherwise no backup file is made for the user's
bookmark file.
 
The original code used `write-file'.  The change was made to use
`write-region' on 2005-11-12:
 
 Revision ID: kfogel <at> red-bean.com-20051112203022-g0v8q4n9urlfew61
 
 (bookmark-write-file): Don't visit the destination file, just write
 the data to it using write-region.  This is similar to revision 1.32
 of saveplace.el, but with an additional change to avoid visiting the
 file in the first place.
 
I'm no expert on this, but from what I see by experimenting, using
`write-region' means that no backup is made, and using `write-file'
creates a backup.  It is important for users to be able to have a backup
for their bookmark file.
