Hmmmm, as C is not all that object-oriented that lets us say "commit
objects have generation() method", a plain vanilla function whose
name is generation() is a bit overly vague. The field name this
helper function replaces, .generation, is very localized to a commit
"object" and does not have such a problem.
We probably need to choose a better name in the previous step to fix
it.
