Pattern vars accessed from Lisp now dynamic.
* eval.c (set_dyn_env): Static function becomes external.
* eval.h (set_dyn_env): Declared.
* match.c (eval_with_bindings, eval_progn_with_bindings):
Evaluate Lisp code in null lexical environment. Instead
install the pattern variables as dynamic, so they shadow
global variables. A compatibility check for 121 or earlier
provides the old behavior.
* txr.1: Document scoping rules, and added compatibility
notes.
