[Distutils] easy_install feature request

[Thomas Heller]

The more I manage the third-party packages I have installed with easy_install,
the more I like that I never have to fiddle around in the file system.  (Except
when I want to free the space that a no-longer needed package consumes,
"easy_install -m <package-name>" works fine).

However (since I'm playing around with support for eggs in py2exe), it is not
possible to reinstall an already installed (by it multi-version or not) package
in zipped or unzipped form by using easy_install.  I always have to delete the package
in the file-system and then call 'easy_install -z|-Z package'.
