commit messages often start with an unuseful line

It behaves as if two systems were one line off from each other about the start/end of some text - most of the time.
It occurs intermittently, but my history for is currently filled with it: 15 out of the last 50 commits.
I was prompted to update to the latest version at start and did so.

    fix: Improve logging for capital gains calculation

Aider version: 0.58.1 Python version: 3.12.1 Platform: macOS-13.0.1-x86_64-i386-64bit Python implementation: CPython Virtual environment: No OS: Darwin 22.1.0 (64bit) Git version: git version 2.39.2 (Apple Git-143)

Aider v0.58.1 Main model: openrouter/anthropic/claude-3-opus with diff edit format Weak model: openrouter/anthropic/claude-3-haiku Git repo: .git with 26 files Repo-map: using 1024 tokens, auto refresh

Thank you for filing this issue.

Looks like Haiku sometimes decides to not follow instructions (see here -> https://github.com/paul-gauthier/aider/blob/main/aider/prompts.py#L15) and start yapping with the additional first line.

You can either try to also use Sonnet-3.5 for the weak model to generate the commit messages and hope it will follow those instructions with -> --weak-model claude-3-5-sonnet-20240620

Or you can try using this prompt (adapted from this shell function which never let me down so far with Haiku to generate commit messages), which I propose here -> #1852

You can try it out with these instructions ->

pip install git+https://github.com/fry69/aider@commit-prompt-fix

# or

pipx install git+https://github.com/fry69/aider@commit-prompt-fix --force

Please let me know if this works better for you.
