And nothing shows up in the body, because git truncates at the NUL we

But you cannot hide from "cat-file commit" ;-)

With the recent push to more (perceived) security, it may probably make
sense to teach "log" family commands to quote-show ^@ and what is behind
in their output by default, perhaps with an option to turn it off.

What about NUL in file name in tree objects? Suppose the original tree
has an entry named "goodthing". With luck, they might be able to
create a new tree object with the entry renamed to "evil\x001234" that
has the same SHA-1. Could that possibly cause any problems?
