New submission from Michael Klatt <michael.d.kl...@gmail.com>:
The behavior of os.path.join() regarding path separators does not match the
documentation. This affects Python 3.6, and goes back to at least Python 2.7.
>From the documenation:
"The return value is the concatenation of path and any members of *paths with
exactly one directory separator (os.sep) following each non-empty part except
the last, meaning that the result will only end in a separator if the last part
is empty."
To me, this means that join will remove extraneous separators from the path,
and that the only way to produce a trailing separator is to use join "" as the
final path segment.
I expect `os.path.join("/abc//", "def/")` to produce the string "/abc/def"
based on the documentation, but what it actually produces is "abc//def/".
