How big is the result? The individual deltas in the bundle won't be
compressed, so if it's not 10G, it won't contain your large files.

Those look like our binary delta chunks.

Much to my surprise, it is possible to commit files > 2G and even verify
and clone the result locally. And you can even commit changes to such
files, but you won't be able to check out those changes as the delta
applying code will get confused. I'll be adding a check to make sure we
refuse to commit such large files in the future.
