ambiguities where options (integer in Python) are interpreted as
initial states.

check that the clauses of the disjuncts are Fin-less: they aren't
(this was discovered while discussing with Jan and Fanda).
Suggested by František Blahoudek.
* spot/twaalgos/simulation.cc: When doing forward simulation with
state-based acceptance as input but transition-based acceptance as
output, pull acceptance marks on incoming edges instead of pushing
them to outgoing edges.

structures, and fix failure of get_accepting_run() to compute
accepting runs in SCC that are accepting due to the self-loop
optimization of scc_info.
