Comment (by joyously):

 > Remove redundant `ltrim()` from `path_join()`

 Isn't it only redundant in the second return in `path_join`? It seems like
 the `ltrim` should be used in the first return. There is no test case for
 a path with multiple slashes.
 Also, the `path_is_absolute` function checks for `/` or `\`, so should
 these paths be normalized first, before joining them?
