@regehr @jripley Our genomics library suffered from this on x86-64 a while back: data structures with unaligned uint32_ts crashed when user code was compiled with vectorisation. It was a shame that these uint32_t CIGAR entries weren't aligned in the first place, which I've long used as an example of the perils of bioinformaticians single-handedly designing formats without any input from anyone with a CS background… #ThisIsBioinformatics

@u24 @ramsey @jamalix @b0rk This was one of my biggest confusions when I first started with git: it IS the same. Recording the fact of the rename is just an illusion provided by the diff mechanism searching for similar text in differently named blobs. See the diff -M option and friends, and config diff.renames et al.
