Can you tell me what the zstd invocation is that corresponds to the default invocation of bzip3, which uses block size 16 MiB (according to the man page)?
I got some really good results with bzip3 compression Wikipedia XML dumps, and I would like to check if it's actually better or if I was just calling zstd wrong.

If you want a 16MB window, use `--long=24` (2^24 is 16M). (I believe this is larger than the default window for zstd level 3, but smaller than the default window at higher compression levels.)
