[IPython-dev] IPython help systems fails with 0.7.1 under windows

[Vivian De Smedt]

Dear All,

This is a bug report. I just download the last IPython version 0.7.1.

As some of you know I'm running IPython under windows and it seems that
that the help functionality of IPython is broken on my station.

the following code:

    import os
    os ?

lead to a huge stack print that end with:

   1849         if handler is not None:
-> 1850             return handler(line,continue_prompt,pre,iFun,theRest)
   1851         # Emacs ipython-mode tags certain input lines
   1852         if line.endswith('# PYTHON-MODE'):
