Trunk was already pretty 8-bit clean; but I'm still
removing the --full from the flex command so everything
is uniform.

  This patch fixes a problem with 8-bit input to the ast_expr2 scanner.
  
  The real culprit was the --full argument to flex
  in the Makefile! This causes a 7-bit scanner to be
  generated.
  
  I reviewed the rules and found one rule where I needed
  to specifically include 8-bit chars for a token.
  
  I tested against the text supplied by ibercom, and 
  all looks very well.
  
  This has been there a surprisingly long time!
