The repository does not have an empty Scripts/ (and maybe this is 
Windows specific).  It does have Lib/site-packages.

Removing added files is different from reverting changes to existing 
files.  To clean up, after running 'git clean -d -n', I ran
F:\dev\3x>git clean -d -f
Removing Lib/site-packages/blurb-1.0.0.post1.dist-info/
Removing Lib/site-packages/blurb.py
