Jan Nieuwenhuizen 2823fca025 Avoid gratuitous consing with begin and quasiquote. 
* mes.c (apply_env, main): Call begin rather than eval with cons'ed
  symbol begin.
* module/mes/mes-0.mes (apply-env): Likewise.
* quasiquote.c (add_unquoters): cons global unquoters rather than
  creating it fresh.
* module/mes/mes-0.mes (add-unquoters): Likewise.
