I came across an issue that I am wondering whether I should report as an
issue.  If I have a directory, say:

  base='C:\\Documents'

and I use os.path.join() as follows:

  join(base, '..\\..\\', 'build', '')

It rather defeats the purpose of os.sep if you include it in a part of
the path.  What you mean is better expressed as

  join(base, '..', '..', 'build', '')

(and base includes it too, but I can't suggest an alternative because I
don't know your intent is far as defaults go.)

Thanks for your input but while that part of my path may not be to your
liking, it works fine and does not seem to be relevant to my concern,
which is that join appears to treat os.sep as an absolute path, which it
is not.

If it starts with the path separator, then it's absolute (well, absolute on that drive).

Open a Command Prompt window and it'll open in the %HOME% folder. Then type "cd \" and it'll put you in the root folder.
