Thanks a lot Ville : with your hints, I found how to do it, but I didn't 
manage to remove the inserted command, i.e. remove the hook. Here's what I 
did :

def foo_pre_prompt_hook(self):
 	ip = IPython.ipapi.get()
 	ip.set_next_input("foo: ")

def qsetPrompt(stv = True):
 	ip = IPython.ipapi.get()
 	if stv:
 		pass # What do I need to put here to remove the hook ?
