Some hair splitting again on the editorial side.

In 2.8, RDF Collection, it simply says that (1 ?x 3) is an alternative for

_:b0  rdf:first  1 .
_:b0  rdf:rest   _:b1 .
_:b1  rdf:first  ?x .
_:b1  rdf:rest   _:b2 .
_:b2  rdf:first  3 .
_:b2  rdf:rest   rdf:nil .

It may be worth adding (or reformulating the text) that a triple pattern:

:a :b (1 ?x 3).

is then *replaced* by the triple:

:a :b _:b0.

where _:b0 is the one above (ie, the (1 ?x 3) is not mechanically replaced by
the stuff above, it would be syntactically incorrect because it would lead to a
duplicated full stop...).

It may be obvious but I think it is worth making it clear.
