//ww:error c "expected ), got IDENT" ww "expected ')' after for"
// 2-clause `for (cond; post)` is a form in neither Go nor the cstage
// grammar — the old wwstage accept was a parser bug (aligned DOWN,
// rule 10 / the Go-derivation ruling). Both parsers consume the stray
// ';' and then demand ')'.
