python-describe-symbol fix for python.el and emacs.py

[Steven Huwig]

Hello,

Using the copy of emacs.py I just pulled from CVS, the following  
behavior occurs:

>>> from Tkinter import *
>>> emacs.ehelp("Frame")
no Python documentation found for 'Frame'

None
>>>


If you add the optional globals and locals parameters to the eval  
call in emacs.ehelp(), and to the invoking python-describe-symbol  
function in python.el,  emacs.ehelp() will find the help in these cases.

Thanks,

Steven Huwig
