You know, all this path separator and list complication isn't really necessary, when you can just take the os.path.dirname() of the return from commonprefix().
Perhaps we could just add that recommendation to the docs?

I'd guess not, but that's not the point. The point is that you can use both / (aka ntpath.sep) and \ (aka ntpath.altsep) in Windows pathnames. See my patch (issue 4755) for a version of os.path. which works as at least I expect and should work cross-platform. Skip
