Well, I don't know how you're counting that. All the code for dealing
with the include stack is in the generate_lines function, which is 10
lines long. The remaining code is then simpler for not having to deal
with it. In the original version, I can't identify which lines are
"dealing with the include stack" because they're so intertwined. For
example, all the sporadic code checking for line == None or line !=
None only need to exist because of the include stack.
