This will unfortunately be quite a pain to maintain going forward, as we
now have to be aware of updating this site every single time we add a
new option that accepts a parameter.

I don't really have a good idea for how to fix that reliably though, I
have to admit. Maybe we should just mostly ignore this edge case and
always complete references, unless we have seen a `--`? That can be
checked rather easily via `__git_hash_doubledash`.

That'd still be a huge win compared to the status quo, and if we really
care about making this work properly we can still iterate.
