move definition of platform dependent path related variables from os.py
to platform dependent path modules (ntpath, etc).
Library
-------
+- the platform dependent path related variables sep, altsep, extsep,
+ pathsep, curdir, pardir and defpath are now defined in the platform
+ dependent path modules (e.g. ntpath.py) rather than os.py. These
+ variables continue to be available via os.path (see
+ <http://www.python.org/sf/680789>).
+
- array.array was added to the types repr.py knows about (see
<http://www.python.org/sf/680789>).
