In any case, as a parting comment, http://bugs.python.org/issue1232023 seems to have been committed with no tests and the only documentation being a one liner in the NEWS.txt file. Was there other discussion of this?
It probably should have gone into What's New as well, but it was too late for that at the time the bug was filed.
(Incidentally, export PYTHONPATH= or its Windows equivalent circumvents whatever the patch was trying to achieve, so the change doesn't seem to make sense anyway...)
The change was fixing a clear bug: blank path elements were being introduced into the path _unintentionally_ and unexpectedly. Setting PYTHONPATH would be a way to do it intentionally.
