When you do Object? in Jupyter or Ipython, pinfo is the name of the magic command that gets called.

I will likely let this get out of sync with the upstream Ipython repo, so if you want to use this I suggest you make your own fork of the IPython repo and manually apply the 3 line patch on top. However if you do want to install this version, do
$ git clone https://github.com/TomHodson/ipython.git
$ cd ipython
$ pip install -e '.[test]'
