While writing an ignore library, I encountered subtle bugs caused by Rust’s Path behavior.

• ends_with in Path is different from ends_with in str: If you try to check whether a Path is a directory by its final character, you’ll find that path.ends_with("/") returns false.

• Path::strip_prefix also consumes the final slash: If you have a directory marker at the end, such as /Users/emre/mydir/, and pass it to strip_prefix("/Users/emre"), you’ll get mydir instead of mydir/.
