aider: get_input now treats control+enter as a newline with prompt toolkit KeyBindings.

# Aider chat conversation:

USER: can we have `get_input` treat control+enter as a newline with prompt toolkit KeyBindings

ASSISTANT: To implement this feature, we need to modify the `get_input` method in the `InputOutput` class in the `aider/io.py` file. We will use the `KeyBindings` class from `prompt_toolkit.keys` to bind the `Control+Enter` key combination to insert a newline.

Here are the changes:

```python
aider/io.py
<<<<<<< ORIGINAL
from prompt_toolkit.shortcuts import CompleteStyle, PromptSession, prompt
=======
from prompt_toolkit.shortcuts import CompleteStyle, PromptSession, prompt
from prompt_toolkit.keys import Keys
from prompt_toolkit.key_binding import KeyBindings
>>>>>>> UPDATED

```python
aider/io.py
<<<<<<< ORIGINAL
            session = PromptSession(**session_kwargs)
=======
            kb = KeyBindings()

            @kb.add(Keys.ControlJ, eager=True)
            def _(event):
                event.current_buffer.insert_text('\n')

            session = PromptSession(key_bindings=kb, **session_kwargs)
>>>>>>> UPDATED
```

This code creates a new `KeyBindings` instance and adds a binding for `Control+Enter` (represented by `Keys.ControlJ`) to insert a newline. Then, it passes this key bindings instance to the `PromptSession` constructor.
