Extending your code to automatically handle any set of delimiters (not
just the <<chunkname>>= we currently use) was the goal.  I would like
to write notangle in lisp once and be done with it ;-).

No.  Thanks for the link, I'll check it out.  Kai sent me some finite
state machine code as well, and I am working on trying to understand
it.  I was trying to deviate from your code as little as possible
because your code has proven itself fast and I didn't want to
accidentally introduce any performance hits.

That's what I'm trying to achieve.  I guess I need to think more about
how to set up the macros.
