Little things that matter in language design
Many binary formats are compressed by default. This usually prevents computing deltas. Are these tools clever enough to transparently uncompress revisions before comparing?
Support large repositories!

Every time I tried this, the delta was almost as big as the file itself. Would you have counter-examples?

This has been discussed several times (especially in the context of handling things like .odf files that are compressed XML). What needs to be done to handle formats like this is well understood. Git even has the mechanism to flag files as being of a specific type and call arbatrary tools (external scripts/programs) to handle different file types.
unfortunately, nobody has good, simple examples of this that I am aware of. It's possible, but will take some git-fu to get setup.
