As a more general approach, would it be worth considering an addition
to itertools which took an iterator which generated "blocks" of items,
and split them on a subsequence? It's a generalisation of the basic
pattern here, and would be able to encapsulate the fiddly "what if a
separator overlaps a block split" logic without locking it down to
string manipulation...

Or does that count as overgeneralisation?

Paul.
