Changes in 'python' command behavior
------------------------------------
* In a posix shell, setting an environment variable to an empty value is
generally equivalent to not setting it at all. In particular, this is true
for the :envvar:`PATH` environment variable. However, setting
:envvar:`PYTHONPATH` to an empty value was *not* equivalent to not setting it
at all: setting :envvar:`PYTHONPATH` to an empty value was equivalent to
setting it to ``.``, which leads to confusion when reasoning by analogy to
how :envvar:`PATH` works. The behavior now conforms to the normal posix
convention.
