OK, I think I got it finally... Please svn up and let us know.  Here's
what I'm getting for simple tests:

ZeroDivisionError: integer division or modulo by zero
***************************************************************************
Exception in the IPython Engine.

Engine action that caused the error:

engine: 0
method: execute(lines)
lines =

os.chdir('/home/fperez/ipython/test/ip1')
import err
err.bad()
#abd snytxx


Full traceback:

Syntax errors are reported with a clumsy traceback:

But at least now we are getting all the necessary info across, even if
for syntax errors the report isn't the nicest.
