The indentation's wrong. The line starting "for subkey in..."
should be indented to the same level as the line above, placing
it within context of the "with open (...):" from a few lines
above. I've just checked the email I sent with that in, and it
looks ok (on my email client) so I can only imagine that
one of the various email clients / servers between us has
munged the indentation.
