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!
