Whooopss.. replied too fast...

This seems to work:

>>> for i in [3, 2, 1, 0]:
...     print (i, 1.0/i)
...
Traceback (most recent call last):
...
ZeroDivisionError: float division

it seems that if the expected result is a traceback, the doc result must
starts with the traceback keyword:

"""
The expected output for an exception must *start* with a traceback
header, which may be either of the following two lines, indented the
same as the first line of the example:

Traceback (most recent call last):
Traceback (innermost last):
"""
