Indeed, ipython imports help upon starting.  So by the time scipy tries to 
modify things, the help ipython sees is already the default one.

I've noticed in general that, because of the lazy import mechanisms of scipy, 
often I need to do things like hitting tab twice, at least the first time I 
try them.  I realize the rationale for the lazy import system, so I don't know 
if this is something which can even be fixed at all.  But if there are any 
changes which ipython can make to improve the situation, and someone can at 
least point me in the right direction, I'll gladly give it a try.
