That's a rather unusual binary file, no? Indeed, it will completely
defeat our delta algorithm.

But a binary that contains any of the following will have plenty of
linefeed bytes (0x0a):

- compressed data of any sort
- raw binary data with non-contrived distributions
- machine code
- embedded text

..so if you can find a real-world 200k file that doesn't have enough
0x0a bytes in it to be digestible, I'll be amazed.
