    With this change the output of

    uses less than (n+1)^2 transitions when it used
    exactly (n+1)*(2^n) transitions before.
    
    * src/tgba/tgbatba.cc (tgba_tba_proxy_succ_iterator): Merge
    transitions going to the same states if they are both accepting or
    if neither are.
    (state_ptr_bool_t, state_ptr_bool_less_than): Helper type to
    store a transition in tgba_tba_proxy_succ_iterator.
    * src/tgba/tgbatba.cc, src/tgba/tgbatba.hh
    (tgba_tba_proxy::transition_annotation): Remove.  We cannot
    implement this method if transitions are merged.
