Boy, will *that* break Python!! That is, it fails to catch a number of
significant differences between the files (especially the "-b" & "-B").

Also, while "-b" is o.k. for most non-Python code, you really, *really*
don't want to be using "-w", since it fails to distinguish between "FOOBAR"
and "FOO BAR".
