Critical Error when converting python notebooks that contain `-` in the name about nbconvert HOT 5 CLOSED

It looks like it may be something with how the jupyter script is passing along args. I get the same error as the issue if I use jupyter nbconvert, but if I invoke the module directly, I get this: https://gist.github.com/sccolbert/4105b6e24e0ca42cf2cd
I went down the path of invoking directly, just so I could debug the thing, since jupyter starts a new background shell
(the error in the gist is appropriate, since my version of the nb file is an empty { })
but running the jupyter command directly does error: https://gist.github.com/sccolbert/82f6f4e629768dea1ef1
The problem is what the jupyter command is passing to os.execvp: https://github.com/jupyter/jupyter_core/blob/master/jupyter_core/command.py#L132
printing that on the command of interest, we get:
jupyter-nbconvert ['nbconvert', '0 - name.ipynb', '--to', 'slides', '--post', 'serve']
notice that the second arg is no longer quoted
Q.E.D.
Not sure what the best solution is, short of traversing the args and re-quoting the ones with spaces before exec'ing the subprocess
