Restore some functionality of the sphinx directive....

Restore some functionality of the sphinx directive. See The issue is in 2 part, before IPython 7.0 the input splitter was state full, this was (in part) due to readline. The second part is that because of this, we had to be a bit adressive of what was considered complete code (it had to have 2 new line). This is now not required anymore as we can submit stuff as a whole. I hope that this fixes that. I have another fix in mind that count (and reset) the number of consecutive blank line, but that will be more complicated end code.
