ah so the "definition" of 2 changed. It used to be:

RETURN VALUE
        diff returns 0 if the files are identical or 1 if the files differ.  If
        one or both of the files cannot be opened, then the return value is set
        to 2.

Yes it does restore the behavior.  I do not really understand what the
description of -q/--brief has to do with binary files (I just tested
that case), as the output stays the same for them with or without -q,
only the return code seems to change. Funny thing;-)

Thanks a lot for the fast reply!
