was trying to have setuptools fix distutils' broken filename handling that
assumes people haven't put punctuation in their distribution names,
including '-' (which prevents unambiguous parsing of distribution names).
However, bdist_rpm's attempt to guess a source distribution's filename
isn't compatible with this fix, without making other changes.  I decided
therefore to drop the fixes for the sake of backward compatibility, but
monkeypatch bdist_rpm so that it runs "egg_info" first, to ensure that any
--tag-svn-revision or other tagging options take effect.
