The unwritten API contract expected of a VFS.getcwd() by mp_vfs_getcwd() is that its return value should be either "" or "/" when the CWD is at the root of the VFS and otherwise start with a slash and not end with a slash. This was not correctly implemented in VfsPosix for instances with a non-empty root - the required leading slash, if any, was cut off because the root length includes a trailing slash. This would result in missing slashes in the middle of the return value of os.getcwd() or in uninitialized garbage from beyond a string's null terminator when the CWD was at the VFS root.
