“code foo.ipynb” should set the directory where the notebook is as the working directory

[ronglums]

One nit – if I type “code foo.ipynb”, I expect that the Jupyter / python current work directory to be set to the same directory as foo.ipynb vs. some random directory. I seem to recall that you had a good reason why that’s the case, but this is very unexpected if you’re used to how “Jupyter notebook foo.ipynb” works.

Opening a loose (no folder .ipynb file sets to the location of the .ipynb file now).
