Manual erratum: example in `index`

[rickyboy]

As reported by github user https://github.com/fuxoft">fuxoft in https://github.com/kosh04/newlisp/issues/3">//https://github.com/kosh04/newlisp/issues/3.

In the documentation of the "index" function, the last example line says:



(select '(1 10 3 6 4 5 11) '(1 3 6)) → (1 3 6)



This is wrong. The returned value is not (1 3 6) but (10 6 11).

The culprit can currently be spotted here:
