[issue12104] os.path.join('/some/path', '') adds extra slash at end of result

[Brian Curtin]

Brian Curtin <brian at python.org> added the comment:

This is intentional. See the implementation of join in Lib/posixpath.py and the Windows implementation in Lib/ntpath.py which also includes a comment explaining why.

# path is not empty and does not end with a backslash,
# but b is empty; since, e.g., split('a/') produces
# ('a', ''), it's best if join() adds a backslash in
# this case.
