RFR: 8221709: replace use of style blockListLast

[Jonathan Gibbons]

Looks good to me.

It's nice to see this simplification, especially the simplification in 
the builders to eliminate the computation of the isLastContent parameter.

And yeah, it's sort of funny that blockListLast was was same style as 
blockList.
