Subject: bug#19140: dir-locals-collect-variables discrepancy in handling non-file buffers 
Date: Tue, 30 Dec 2014 19:45:57 +0000

	Please consider the revised patch MIMEd.

	* lisp/files.el (dir-locals-collect-variables): Use
	default-directory in place of the file name while working on
	non-file buffers (as hack-dir-local-variables already does.)
