We definitely can do better.
One way would be to set the prompt regexp dynamically using the values
of sys.ps1 and sys.ps2. But then we also need to be careful as those
values for ipython are a lie:
$ ipython
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
Type "copyright", "credits" or "license" for more information.
IPython 1.2.1 -- An enhanced Interactive Python.
? -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help -> Python's own help system.
object? -> Details about 'object', use 'object??' for extra details.
In [1]: import sys
In [2]: sys.ps1
Out[2]: 'In : '
Perhaps the best way to go is a mixture of the current way and
dinamically expanding `python-shell-prompt-regexp` with sys.ps1 and
sys.ps2. I'll give it a try in the next few weeks and follow up once I
see how it goes.
