repo.status() appears to be broken?

I'm running repo.status().items() in a pre-commit hook using the -a flag (git commit -a -m "Test"), and I get a result that looks like this:

[('config/git_hooks/pre-commit', 256), ('bin/run_flake8', 256)]

If I run git status in that same process, I get:

On branch ops_1331_fix
Your branch is ahead of 'origin/ops_1331_fix' by 2 commits.
  (use "git push" to publish your local commits)
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    modified:   bin/run_flake8
    modified:   config/git_hooks/pre-commit

In other words, pygit2 is reporting those files as not being staged, and git is reporting them as being staged. Why the discrepancy?

Inizia riproducendo la discrepanza con repo.status().items() nel pre-commit hook usando git commit -a, quindi confronta il risultato con git status per i due file elencati. Leggi la pygit2 status API e il comportamento correlato di libgit2; il lavoro è completato quando spieghi perché i file nell’area di staging ricevono lo stato 256 e correggi la discrepanza se si tratta di un bug.
