…ocesses section Non-lexical lifetimes were added in rust 1.31 (2018 edition) and 1.36 (2015 edition) which have been available for over a year (1.36 released 4 July 2019). This small change updates the code sample and removes a comment explaining the use of scoping to assist the borrow checker. The removed comment was helpful to explain the reasoning behind the local scoping, but was ultimately off topic for the section. core::str<_>::trim_right was deprecated in Rust 1.33 and superceded by trim_end(). Update file4.rs, and file5.rs to use trim_end.
