pub fn parse_context_restore(ps: &parse_stack)Expand description
Direct port of parse_context_restore(const struct parse_stack *ps, int toplevel) at Src/parse.c:326.
Inverse of parse_context_save. Restores lexer-side state +
pending heredocs + Rust-only counters from ps, then clears
errflag & ERRFLAG_ERROR per parse.c:354.
WARNING: param names don’t match C — Rust=(ps) vs C=(ps, toplevel)
