Yes, that could be a possibility.

Right.  As soon as you move from a straight overall re approach to something
more stateful, such as identifying and splitting off doc header, title, toc
etc, you can do better handling.

I'll consider this for a later version, but it should be a major re-write,
to change the approach, rather than trying to tweak this in here and there,
I think.

Agreed.  This might be an easier fix than the rest.

Right.
