Right, but it's extremely unlikely to happen by accident. I was
suggesting that there might be a security issue. I could fairly easily
make my git commit match a prefix intended to uniquely identify your
git commit if I set out to do so.

There are projects that might have to consider that possibility,
though perhaps we're not one of them.
