Subject: [PATCH] aider: Added extra backticks to the start and end of the
 `show` variable to ensure proper formatting.

# Context:
USER: do the todo
ASSISTANT: To complete the TODO task in the `diff_partial_update` function, I will find the longest string of backticks (`) that start a line in the `diff` variable. I will then add one more backtick to the start and end of the `show` variable to ensure proper formatting.

Here are the changes:

```python
aider/diffs.py
<<<<<<< ORIGINAL
    for line in diff:
        pass

    diff = "".join(diff)
    if not diff.endswith("\n"):
        diff += "\n"

    show = "```diff\n"
=======
    max_backticks = max(len(line) - len(line.lstrip("`")) for line in diff.splitlines())
    extra_backticks = "`" * (max_backticks + 1)

    diff = "".join(diff)
    if not diff.endswith("\n"):
        diff += "\n"

    show = f"{extra_backticks}diff\n"
>>>>>>> UPDATED
```

```python
aider/diffs.py
<<<<<<< ORIGINAL
    show += diff + "```\n\n"
=======
    show += diff + f"{extra_backticks}\n\n"
>>>>>>> UPDATED
```

These changes will find the longest string of backticks at the start of a line in the `diff` variable and add one more backtick to the start and end of the `show` variable.
