What should it do in the opposite case: where the path is a relative
path on another drive? I.e. os.path.join('c:\\abc','d:efg'). This is
archaic, sure, but if we're going to say it's always equivalent to "as
if the first argument were the cwd", this needs to be handled too.
Fortunately, I don't think there's any way to specify this with a UNC
share.
