Greetings, All!

I have strange (to me) issue that I'm not entirely sure how to interpret.

Let's say I have two versions of the same batch file:

The old version from CVS:

> rem $Id: backup.bat,v 1.1 2007/07/17 01:53:30 Daemon Exp $
> rar a -ag-YYYY-MM-DD_HH-MM -- MinerTimer @MinerTimer.list

The new version I've imported to Subversion:

> @echo off
> rem $Id: backup.bat 10 2010-09-30 01:22:14Z anrdaemon $
> rar a -ag-YYYY-MM-DD_HH-MM -- MinerTimer @MinerTimer.list

When I'm comparing them with my usual macro
diff -bdu -x "CVS" -x ".svn" -I "\$Id.*\$" -I "\$Revision.*\$" -I "\$Date.*\$" -I "\$Author.*\$" --strip-trailing-cr -- '1/backup.bat' 'backup.bat'

It telling me that $Id$ lines are differ.
But when I remove the "@echo off" from second file, it telling me that
files are "identical" (the expected result).

Having hard times dechiphering man diff, so if anyone can enlighten me in
simple words on the matter, I'd appreciate help greatly.
