[Chandler-dev] "pystack" in gdb for Python 2.5

Yesterday, I was trying to get the Python gdb macros to work in  
Chandler's python, and finding that the very handy "pystack" command  
wasn't working at all.

Anyway, I figured out a tweak to the "pystack" macro that got things  
to work for me. The patch is below for anyone else who needs it; I'm  
not sure if it fixes a typo, or if the bug is a result of symbols  
shifting around in the python 2.5 binary. I'll probably follow up on  
the python IRC channel at some point.
