Thanks - this is a bug in LLM core, moving it there.

This happens with Claude 3.5 Sonnet and GPT-4o, so I think it's a bug in LLM.

I'm not sure why this test didn't catch this:

https://github.com/simonw/llm/blob/122265a3d2131a7140911c2a3d99ad045d61c847/tests/test_chat.py#L20-L31

I've manually tested the fix and confirmed that it works. I'll need to rethink this when I add attachment support to llm chat directly.

Manual testing:

% llm chat -m gpt-4o-mini
Chatting with gpt-4o-mini
Type 'exit' or 'quit' to exit
Type '!multi' to enter multiple lines, then '!end' to finish
> A short pun about pelicans
Why don’t pelicans ever get invited to parties? Because they always bring their own bag!
> banana slugs
What do banana slugs wear to impress each other? Slug-phy attire! 🍌🐌

And llm logs -c now returns:

This seems to be a duplicate of #597 so I'll close that too -- glad to see it fixed, thanks Simon!
