/// \brief Print reachable states in LBTT format.
///
/// Note that LBTT expects an automaton with transition
/// labeled by propositional formulae, and generalized
/// Büchi acceptance conditions on \b states. This
/// is unlike our spot::tgba automata which put
/// both generalized acceptance conditions (and propositional
/// formulae) on \b transitions.
///
/// This algorithm will therefore produce an automata where
/// acceptance conditions have been moved from each transition to
/// the previous state. In the worst case, doing so will multiply
/// the number of states and transitions of the automata by
/// `2^|Acc|`

. where `|Acc|`

is the number of
/// acceptance conditions used by the automata. (It can be a bit
/// more because LBTT allows only for one initial state:
/// lbtt_reachable() may also have to create an additional state in
/// case the source initial state had to be split.) You have been
/// warned.
///
/// \param g The automata to print.
/// \param os Where to print.
