Incorrect detection of modified/renamed files

Test code:

import pygit2
repo = pygit2.Repository(pygit2.discover_repository(<repo_path>))

status = repo.status()
for filepath, flags in status.items():
    print(filepath, flags)

Running Result:

child.py 128
example.py 128
mvv.txt 513
mvvv.txt 4
name2.py 128
parent.py 128
x/mvv.txt 128
x/mvvv.txt 513
x/parent2.py 128
xname.py 128
zname.py 512
zname1.py 128

However, git status given me the result as:

On branch master
Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
        renamed:    mvvv.txt -> mvv.txt
        new file:   x/mvvv.txt

Changes not staged for commit:
  (use "git add/rm <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        deleted:    mvv.txt
        deleted:    x/mvvv.txt
        deleted:    zname.py

Untracked files:
  (use "git add <file>..." to include in what will be committed)
        .idea/
        child.py
        example.py
        name2.py
        parent.py
        x/mvv.txt
        x/parent2.py
        xname.py
        zname1.py

Which contains the renamed records.

Why this happened?
(If you want the test repo, I can zip it and send to your team mail if anyone provide me one.)

从所示的 Python 代码片段和入口点 repo.status() 开始，然后针对相应的 git status 输出重现列出的 flags。确定缺失或不同的重命名记录是预期行为还是 bug，并记录预期结果和可复现的验证路径。
