Version 3.1.1

The docs says it will be list type of return value: https://gitpython.readthedocs.io/en/stable/reference.html?highlight=blame#git.repo.base.Repo.blame

But instead of it i've got a string:

In[2]: from git import Repo
In[3]: from django.conf import settings
In[4]: r = Repo(settings.BASE_DIR)
In[5]: bl = r.git.blame('HEAD', 'users/utils.py')
In[6]: type(bl)
Out[6]: str

Version is similar as in the docs.

(venv) a@a:~/Workspace/git_test$ pip freeze | grep Git
GitPython==3.1.1

Is that incorrect docs or bug in the library?
