This is part of a demonstration that deals with people who've stuck

The problem is that the rule sets are generated programatically from a
simple list and the analysis needed in order to find and deal with
zero-length assertions is non-trivial, especially as they seem to appear
in cases where the strict ordering of transformations becomes important.

For now, I will go with the current plan. I'll probably be posting the
results as a recipe in a day or two (if I can fix a bug I'm having
related to extended-ASCII characters), and it will be much easier then
to judge if my approach is fundamentally flawed, overambitious, or what.
