    gengtype: do not skip char after escape sequnce
    
    Right now, when a \$x escape sequence occures, the
    next character after $x is skipped, which is bogus.
    
    The code has very low coverage right now.
    
    gcc/ChangeLog:
    
            * gengtype-state.cc (read_a_state_token): Do not skip extra
            character after escaped sequence.
