Re: GitHub Jython repo broken

Last chance to tell me I've done this wrong again before I start 
juggling repositories as per https://github.com/jython/jython/issues/50.

The dry-run (https://github.com/jeff5/jython-whinchat) seems to 
attribute work to GitHub accounts correctly and does not have the 
history problem Jim identified. I will make 
https://github.com/jython/jython-tern by pushing the same thing, 
cherry-picking etc.. (GitHub support have been no help.)

If I'm about to make a mess (because the content is still broken, or 
reusing repo names is a terrible idea), I'll be making that mess this 
evening.
