And it exports the git object hash, not the commit hash, which is kinda
useless without access to the repo. Even if we could get $FreeBSD$ to
expand, it expands to something you need the git tree to do anything with.
There's the git smudge extension which does this, but it's tedious and
cumbersome to use, and the information it preserves is at best indirect.
