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!

Software is harder than hardware so better get it right the first time.
