Log message:
        Fix problem reported by Henrik Grubbstroem in
        <http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>:
        "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
        because the Bison parser reads the second action before reducing
        the first one.
        * src/scan-gram.l (rule_length): New static var.
        Use it to keep track of the rule length in the scanner, since
        we can't expect the parser to be in lock-step sync with the scanner.
        (handle_action_dollar, handle_action_at): Use this var.
        * tests/actions.at (Exotic Dollars): Test for the problem.
