[New-bugs-announce] [issue23535] os.path.join() wrong concatenation of "C:" on Windows

[Eugene Bright]

New submission from Eugene Bright:

Hello!

I found strange os.path.join() behavior on Windows.

It works fine in common case.
>>> os.path.join("C", "filename")
'C\\filename'

But if first argument is "C:" there are no backslashes added at all!

>>> os.path.join("C:", "filename")
'C:filename'

But I expect two inserted backslashes...

>>> sys.version
'3.4.1 |Anaconda 2.1.0 (64-bit)| (default, Sep 24 2014, 18:32:42) [MSC v.1600 64 bit (AMD64)]'

Is there a bug?
Thanks!
