[issue9921] os.path.join('x','') behavior

[Brian Brazil]

Brian Brazil <brian.brazil at gmail.com> added the comment:

The behaviour is a bit more nuanced:
>>> os.path.join('x', '')
'x/'
>>> os.path.join('x', '', 'y')
'x/y'
>>> os.path.join('x', '', 'y', '', '')
'x/y/'
>>> os.path.join('', 'x')
'x'

I'm unsure how to word this best, maybe "non-trailing empty paths are ignored"?
