Subject: [PATCH] aider: Made the two history files optional.

# Context:
USER: make the two history files optional
ASSISTANT: To make the two history files optional, we will modify the `__init__` method of the `InputOutput` class in the `aider/io.py` file. We will set the default values of `input_history_file` and `chat_history_file` to `None`. Then, we will add conditions to check if these variables are not `None` before using them.

```python
aider/io.py
<<<<<<< ORIGINAL
    def __init__(self, pretty, yes, input_history_file, chat_history_file, input=None, output=None):
=======
    def __init__(self, pretty, yes, input_history_file=None, chat_history_file=None, input=None, output=None):
>>>>>>> UPDATED
```

```python
aider/io.py
<<<<<<< ORIGINAL
        session = PromptSession(
            message=show,
            completer=completer_instance,
            history=FileHistory(self.input_history_file),
            style=style,
            reserve_space_for_menu=4,
            complete_style=CompleteStyle.MULTI_COLUMN,
            input=self.input,
            output=self.output,
        )
=======
        session_kwargs = {
            "message": show,
            "completer": completer_instance,
            "style": style,
            "reserve_space_for_menu": 4,
            "complete_style": CompleteStyle.MULTI_COLUMN,
            "input": self.input,
            "output": self.output,
        }
        if self.input_history_file is not None:
            session_kwargs["history"] = FileHistory(self.input_history_file)
        session = PromptSession(**session_kwargs)
>>>>>>> UPDATED
```

```python
aider/io.py
<<<<<<< ORIGINAL
        self.chat_history_file = Path(chat_history_file)
=======
        if chat_history_file is not None:
            self.chat_history_file = Path(chat_history_file)
        else:
            self.chat_history_file = None
>>>>>>> UPDATED
```

```python
aider/io.py
<<<<<<< ORIGINAL
        with self.chat_history_file.open("a") as f:
            f.write(text)
=======
        if self.chat_history_file is not None:
            with self.chat_history_file.open("a") as f:
                f.write(text)
>>>>>>> UPDATED
```

These changes will make the history files optional.
