Subject: [PATCH] aider: Added comments to the regex pattern in
 `aider/coder.py` to make it clearer.

# Context:
USER: can you modify the code to add your earlier regex comments?
ASSISTANT: Sure, I will add comments to the regex pattern in the `aider/coder.py` file to make it clearer. Here are the changes:

```python
aider/coder.py
<<<<<<< ORIGINAL
    pattern = re.compile(
        r"(^```\S*\s*)?^((?:[a-zA-Z]:\\|/)?(?:[\w\s.-]+[\\/])*\w+(\.[\w\s.-]+)*)\s+(^```\S*\s*)?^<<<<<<< ORIGINAL\n(.*?\n?)^=======\n(.*?)^>>>>>>> UPDATED",  # noqa: E501
        re.MULTILINE | re.DOTALL,
    )
=======
    pattern = re.compile(
        # Optional: Matches the start of a code block (e.g., ```python) and any following whitespace
        r"(^```\S*\s*)?"
        # Matches the file path
        r"^((?:[a-zA-Z]:\\|/)?(?:[\w\s.-]+[\\/])*\w+(\.[\w\s.-]+)*)"
        # Optional: Matches the end of a code block (e.g., ```) and any following whitespace
        r"\s+(^```\S*\s*)?"
        # Matches the start of the ORIGINAL section and captures its content
        r"^<<<<<<< ORIGINAL\n(.*?\n?)"
        # Matches the separator between ORIGINAL and UPDATED sections and captures the UPDATED content
        r"^=======\n(.*?)"
        # Matches the end of the UPDATED section
        r"^>>>>>>> UPDATED",
        re.MULTILINE | re.DOTALL,
    )
>>>>>>> UPDATED
```

This should make the regex pattern more understandable.
