On Windows what would you do with this crazy, but valid, path?
c:/etc\\passwd
I don't do Windows, so don't have any idea if there is even an /etc/passwd
file on Windows. 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.<whatever> which works as at least I expect and should work
cross-platform.
