What is a recursive noweb expansion?  I think of the following, which
will cause errors in any situation.

I still (and I think this was my issue last time) don't see how noweb
expansions are more complicated than :var arguments.  That said I agree
that this is an edge case, and I certainly don't have time to make this
change (which you right could be complex) at the moment.
