+ * eval.c (uw_protect_s, return_s, return_from_s): New symbol
+ variables.
+ (op_unwind_protect, op_block, op_return, op_return_from):
+ New static functions.
+ (expand): Removed case for call, if, and, and or. These operators
+ evaluate all their arguments, so the code walker can treat them
+ as a function calls.
+ Added case for block and return-from.
+ (eval_init): New symbols interned. New operator functions
+ registered in op_table.
+
+ * txr.1: Blank sections added.
