FWIW: I think this information also useful (even as separate file in
buildhistory).

In most builds it shouldn't change very often (except the revision) so
the diff shouldn't grow significantly.

There are many reasons why people use different forks of some layers,
some of them are valid (like using own fork to verify some change before
submitting it upstream and showing buildhistory diff how you tested it),
some of them are sad, but still needed _to be shown somewhere_ (like
using fork with important fix, when upstream layer is slow or refusing
to accept the fix).
