  stderr: 'fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]''

ASSISTANT: It seems like there is an issue with the `git diff` command in the `get_dirty_files_and_diffs` function. The error occurs because the 'HEAD' argument is ambiguous. To fix this issue, we can separate the paths from the revisions using '--'. Here's the change:

```python
aider/coder.py
<<<<<<< ORIGINAL
    these_diffs = repo.git.diff("HEAD", "--color", relative_fname)
=======
    these_diffs = repo.git.diff("HEAD", "--color", "--", relative_fname)
>>>>>>> UPDATED
```

This should resolve the `GitCommandError` you encountered.
