To use a slightly different example:

#+BEGIN_SRC python
  import sys
  for i in range(10):
      print "foo"
#+END_SRC

Anything other than 4 spaces per indention level is flagged by python
style/syntax checkers that enforce pep8 (and yes, many flame wars have
been fought on the topic, but there are good reasons for enforcing
consistency). This is an issue when editing code blocks and in tangled
code. Maybe it's primarily an aesthetic thing, but I think that it's
best when possible to set the default to follow the standard
conventions for the language (my python mode certainly seems to think
so!).

I'll do so with pleasure! Thanks again.
