os.path is designed for OS-agnostic path manipulation. The textual 
representation of the output of os.path is irrelevant. If a trailing '/' 
doesn't affect the ability to open the directory or file or os.path.join 
or whatever, it is irrelevant to os.path. If the trailing / does affect 
those abilities, though, it is a bug in os.path.
