Description
repo.index.diff(HEAD, create_patch=True) will also break. However, it works without the create_patch flag.
The following two commands succeed as well.
I have one staged file, one tracked but unstaged file, and some untracked files in my repository.
In [13]: repo.index.diff(None)
Out[13]: [<git.diff.Diff at 0x10d0eab18>]
In [14]: repo.index.diff(None, create_patch=True)
Out[14]: [<git.diff.Diff at 0x10d0eaaa0>]
In [11]: repo.index.diff('HEAD~1', create_patch=True)
