pylint

[Jim Gallacher <ji...@jgassociates.ca>]

I used pylint to assist in cleaning up the indentation mess in util.py. 
I ended up checking all our lib/python/mod_python/*.py code, and 
needless to say the results were.... edifying. The output is rather 
extensive, with a lot noise regarding missing docstrings and the like, 
but I suspect combing through the results might reveal some potential 
gold... or perhaps the exact opposite of gold.

I think it would be good to adopt a policy of pylinting (probably not a 
word, but I like how it sounds :) ) our code on a regular basis.

FYI, if you want to check mod_python.Session you'll need to comment out 
"global rnd_iter" around line 73 in _get_generator(). The use of global 
here exposes a known bug in pylint which causes it hit the maximum 
recursion limit and barf. Just make sure you uncomment that line before 
checking in the code. ;)
