Nothing has happened on this and I suspect because it wasn't
doable. (At least I couldn't figure out how it would be done. But I
figured if it could that *could* it would be a great thing to do.)

So recently, I've added a parameter to pydb so that runv() can get
passed with an Pdb object extended in the way that ipython wants to
extend it. That will be in the next release of pydb (which again can
be timed so that it is no later than the next ipython release).

I've modified ipy_pydb.py so that it now passes in such a Pdb
object. This was the debug session can make use of pdoc and pinfo. It
also uses the ipython debugger prompt (which personally I'm not a fan
of but I guess it makes it ipython consistent.) There is now the
possibility of using the ipython color scheme, but I couldn't figure
out how to get that passed when creating the Debugger.Pdb object.

And in going over IPython/Extensions/ipy_pydb.py I've noticed a couple
of other things. First there should be a check that pydb can be
imported and that there is a late enough version of pydb. 

Below is a patch.
