[Patch] url-cookie-write-file saves versioned backups

[Diane Murray <disumu@x3y2z1.net>]

Versioned backups of the cookies file are being saved (contrary to the
intent of the last changes made to url-cookie.el in revision 1.18),
which causes `backup-buffer' to ask for confirmation to delete those
excess backup files.  Additionally, the error "Local variables list is
not properly terminated" occurs when opening the cookies file.  The
following patch corrects this.

I submitted earlier patches using the email <dsm@muenster.de>, if for
some reason that needs to be known.


	* url-cookie.el (url-cookie-write-file): Insert a newline
	character before the Local Variables line.  Set `version-control'
	to never.
