Thanks for those details! I'll try to reproduce and respond back.
Update: reproduced. Debugging..
Update 2: This was a bug in a recent change in mine. I'm working on a fix, but you can in the meantime go back to the state of the repository on Jan 29th:
$ git checkout e7a95ac658
(You'll need to run this from a clean directory, where you haven't modified any of the files.)
The fix shouldn't be long if you just want to wait. Sorry about this.
Update 3: Ok, it should be fixed now. Do a 'git pull' and try it. And feel free to ping me privately if there's still issues (email in profile). Sorry again.
