I would like the function to be more reusable, aka a method signature similar to pub async fn say_in_reply(&self, channel_login: &str, in_reply_to_message_id: Option<String>, message: String) -> ...

Then also, you should make it so passing None makes it behave exactly like say, and then rewrite say() to use say_in_reply() with a parameter of None. The current function just sends the message out like the privmsg message which might execute commands on accident. Replying to a message with a command wouldn't make sense, so that's why I want it to behave like say() and also be called say_in_response().

The original method signature that accepts a PrivmsgMessage could then be added as pub async fn reply_to_privmsg(&self, reply_to: &PrivmsgMessage, message: String) -> ... which delegates to say_in_reply.

Running rustfmt turns the method signatures into multi-line ones that don't fit with the rest of the functions at all, so I suppose the check can be ignored.

If the method signatures are long then it‘s okay to wrap them like rustfmt wants to. I want to keep the formatting consistent with rustfmt, that‘s why there is the CI check.

I took the liberty to directly edit the changelog to my preferences. There really should be a documented format for the changelog, I apologize. The version heading gets added when a release is made, and I typically try to put relevant issues/PRs as links to the end of the changelog entry.

All looks good now! If you're happy with what I changed the changelog entry too then I'm looking forward to merging this! ❤️

Also, something that I just thought of is that it's not possible to do a /me message in response with the current methods, but I'll probably add that separately when I add the /me sending function.
