[docs] [issue23695] idiom for clustering a data series into n-length groups

[R. David Murray]

R. David Murray added the comment:

I think it would be both helpful and sufficient to add a gloss, perhaps something like: "this passes zip ``n`` references to the *same* iterator, which means zip calls that single iterator ``n`` times for each tuple it creates; zip thus outputs tuples consisting of ``n`` length chunks from the iterator ``s``".
