There's some discussion in the gitattributes manpage, but the short of it is that textconv converts binary input to text, which is then fed through the normal diff mechanism. Whereas an external diff driver is given both sides and can produce whatever output it wants. Textconv is less flexible, but generally way easier to write. -Peff
