[issue38822] Inconsistent os.stat behavior for directory with Access Denied

Eryk Sun added the comment: Here's an implementation of attributes_from_dir() that strips trailing slashes (e.g. "C:/spam///" -> "C:/spam"), which entails copying the const string up to the last character that's not a slash. Rooted paths and drive paths that reference a root directory, such
