Yes. That grammar is a subset of the grammar that results from
replacing the 11.1.6 ' PrimaryExpression : "(" Expression ")" '
production with
"(" GroupElement GroupElements ")"
where GroupElement is defined as any Statement except for Block and
EmptyStatement without a terminal semicolon, and GroupElements is
defined thus
GroupElements : empty
| ";" GroupElement GroupElements
but I thought it was easier to reason about ambiguity and locality of
spec changes for that subset.
