Rollup merge of #142549 - the8472:intersperse-fold-tweak, r=tgross35 
small iter.intersperse.fold() optimization

No need to call into fold when the first item is already None, this avoids some redundant work for empty iterators.

"But it uses Fuse" one might want to protest, but Fuse is specialized and may call into the inner iterator anyway.

README.md

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
