Since the same confusion came up on IRC, I should clarify
that when I said some revision control systems can diff
binary data, I meant being able to do a meaningful diff in
the context of the data.

An example would be being able to see a paragraph has
changed in a word processor file rather than simply seeing
that a range of bytes is different.  A Blender example is being
able to see that Material.001 has been modified.

The very expensive ClearCase is able to do this for certain
application binary files.
