[Distutils] setuptools 0.6c2 released

[Phillip J. Eby]

Please upgrade and report any problems promptly; I plan to release this 
version as 0.6 final if there are no bug reports over the next week or so.

Bug fixes since 0.6c1 include:

* The ``ez_setup`` module displays the conflicting version of setuptools
   (and its installation location) when a script requests a version that's
   not available.

* Running ``setup.py develop`` on a setuptools-using project will now
   install setuptools if needed, instead of only downloading the egg.

* Fix a problem with eggs specified directly on ``PYTHONPATH`` on
   case-insensitive filesystems possibly not showing up in the default
   working set, due to differing normalizations of ``sys.path`` entries.

* Windows script wrappers now support quoted arguments and arguments
   containing spaces. (Patch contributed by Jim Fulton.)

* The ``ez_setup.py`` script now actually works when you put a
   setuptools ``.egg`` alongside it for bootstrapping an offline machine.

* A writable installation directory on ``sys.path`` is no longer required
   to download and extract a source distribution using ``--editable``.

* Generated scripts now use ``-x`` on the ``#!`` line when
   ``sys.executable`` contains non-ASCII characters, to prevent
   deprecation warnings about an unspecified encoding when the script
   is run.
