Aha! I figured out the problem -- it appears that python 2.1 handles
newlines differently:

[Tests]$ python
Python 2.1a2 (#1, Feb  3 2001, 15:37:56) 
[GCC 2.95.2 19991024 (release/franzo)] on linux2
Type "copyright", "credits" or "license" for more information.
>>> spam = "I have a newline\n"
>>> spam
'I have a newline\n'
>>> 
[Tests]$ python2.0
Python 2.0 (#2, Jan 13 2001, 16:29:22) 
[GCC 2.95.2 19991024 (release/franzo)] on linux2
Type "copyright", "credits" or "license" for more information.
>>> spam = "I have a newline too\n"
>>> spam
'I have a newline too\012'
>>> 

Blah, so everytime we had a \012 in a string output before, python2.1
is now generating a \n, so it makes the regression comparisons fail. 
<sigh>

The fun of line breaks never stops.
