Hojun-Cho 241f28c96b syntax: align for-header grammar to cstage (Go's three forms)
The bbdd8bed residue, ruled by the Go derivation (ww's for IS the Go
for; the cstage grammar is the language definition and already the
Go-shaped one):
- bare `for { }` accepted (align UP to parse.c:1023, incl. for-else);
- 3-clause cond and post each omissible — `for (init;; post)`,
  `for (init; cond)`, `for (init;)` (align UP, parse.c:1092-1097);
- 2-clause `for (cond; post)` REJECTED (align DOWN): the form exists
  in neither Go nor cstage (parse.c:1101 eats a stray ';' then
  requires ')'), so the old wwstage accept was a parser bug. The
  reject wording mirrors cstage's failure mode per stage.

forhdr_{brace,emptymid,partial} run fixtures pin the accepted forms
byte-identically; forhdr_twoclause_reject pins both reject fragments.
