When I wrote my review, I didn't consider this use case.
There is no -z format in --batch, which is unfortunate. If we had
one, it would trivially make it possible to do so, and we can even
have paths with LF in them ;-). On the other hand, producing a NUL
separated input is a chore.
Perhaps a new and separate option that is similar to "--batch" but
lacks support for %(rest) and accepts _ONLY_ 40-hex as object name
is the best we can do, then?
