Upgrade 4.0 -> 4.1 / files gone

[Frank Bax]

During audit of upgrade from 4.0 to 4.1, I notice that a couple of files 
that were in etc40.tgz have been removed from etc41.tgz
        /.profile
        /.cshrc
Does this mean we should all delete these files from our systems?  If yes, 
should this be mentioned in upgrade41.html?
