BUG_FIX - It would seem that there is a issue wiht the legacy file listing
  which this commit fits.  I have no clue how any of the other stuff would
  had even worked.
fixed imports on test_svn, look like it was an artifact anyway.
Fixed the various tests that depended on fsencode.
Added a test to run egg_info on a dummy SVN package.
Added a second similar test that invokes the legacy code.
Merged pypa/setuptools into default
Update changelog. Fixes #99.
Added tag 1.3.2 for changeset 076b472a9e3f
Bumped to 1.3.3 in preparation for next release.
For .svn legacy fallback, look for the files in the .svn not the directory.
   (Fixed unexpected deprecation warning from prombredanne)
Also removed the warning from fallback, only a deprecation warning is issued.
Environment.py whitespacing
Created a specialized command executor for tests in Environment.py
Legacy Test in test_egg_info now supresses the deprecation warning.
PythonPath is now explicitly controlled to allow setup.py test on clean
   python installations.  *Fixes Issue #101*
Moved some dummy svn tests from test_sdist to test_egg_info since
   they are egg_info tests.
Downgraded a with statement in a test since we haven't offically dropped
   2.4 support, however, maybe it is time.
Added a test case to ensure no extranuous output on sdist with a simple
   dummy package without rev ctrl.
Earlier Versions of python used gzip and tar directly.  So I need to
make sure they are in the paths for the legacy tests (why did it work before).
Let us hope that svn is not in that directory...
Merged pypa/setuptools into default
Correct changelog entry. Fixes #104.
