  When you see those messages "Files x y differ", that means you have given
the -q option to diff.  Have you perhaps set an alias so that 'diff' now
equals 'diff -q' in your shell and forgotten about it?  The 'alias' command
will show you any aliases currently in effect.  You might also want to check
the output of the 'set' command in case you've defined 'diff' as a shell
function.
