Why not use [f] then?

The short ID may be unambiguous when you create the entry, but it's not 
future proof. The chances of a collision increase over time. You could
disambiguate collisions by walking the history from the root and finding
the first matching commit, but that's in-efficient, why not record it at
the time, as you know exactly what the full name is.

Thanks,
