Description

If the unnecessary_wraps lint triggers, it highlights the entire function (in Rust Analyzer + VS Code at least).

I find this quite annoying: When I'm implementing a new function it can take a bit until I get to the part that can actually fail and return an error. Adding yellow squiggles to the entire function is quite distracting and also obscures other potential warnings:

Proposal:

• Reduce amount of code highlighted. I'm not sure how exactly that works, but maybe the primary span could point only at the result type or the function signature>
• At least inhibit the lint in the presence of todo!()
