TreeEntryChange status is set incorrectly when doing Diff (Deleted instead of Renamed)

I took a diff between 42b22ab5fe78889aae058c3af342ea67b30b48d5 and e315208fe33d43964fb649935e3bbff2275fa101 which are two consecutive commits in Roslyn codebase. As you can see Github shows the status of all changes as renamed but libgit2sharp detects them as deleted.

Steps to reproduce:

1. Clone Roslyn's repo
2. Take a diff between these commits

foreach (TreeEntryChanges change in repo
                    .Diff.Compare<TreeChanges>(commitParents.Single().Tree, commit.Tree, compareOptions: compareOptions))
                {
                    // for all chnages change.Status=ChangeKind.Deleted
                }

Riproduci il diff tra i commit 42b22ab5fe78889aae058c3af342ea67b30b48d5 ed e315208fe33d43964fb649935e3bbff2275fa101 usando il confronto TreeChanges mostrato. Traccia il modo in cui TreeEntryChanges assegna ChangeKind per queste modifiche; il lavoro è completato quando le voci interessate riportano Renamed invece di Deleted.
