Generates SPARQL FROM clauses declaring a query's default-graph dataset.
Emits one from <graph> clause per graph, serialising each via reference and merging it into the default
graph a select or ask query matches against; repeat graphs to build a multi-graph default dataset.
The clauses sit between the query projection and its where clause. Empty graphs, such as those produced by
nil, are dropped first; an empty list yields the empty fragment, leaving the dataset to the endpoint's
default.
