there was confusion as the behavior of os.chmod() on
non-Unix platforms.  Discussion led to a recommendation for
a documentation change, which was submitted as an attachment
to the bug report located here:
http://www.python.org/sf/755617

The submitter of the bug report didn't know how to submit a
patch.  I decided to capture the documentation, add it to
the appropriate tex file, produce a patch, and submit it to sf.
