Description

Support for this breaking change was raised in #7191. This affects sort, sort-by, str contains and find. --ignore-case is used by a few POSIX programs such as less and grep, as well as a few other popular utils like tree and wget. Since long names aren't especially popular (existing primarily for self-documentation purposes), I consider this on the shallow end of the compat-break scale.

Note that the -i short flag is not affected.

User-Facing Changes

See above.

Tests + Formatting

Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

• cargo fmt --all -- --check to check standard code formatting (cargo fmt --all applies these changes)
• cargo clippy --workspace --features=extra -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect to check that you're using the standard code style
• cargo test --workspace --features=extra to check that all tests pass
