* src/twaalgos/sccfilter.hh, src/twaalgos/sccfilter.cc (scc_filter_states): Remove useless acceptance marks while preserving state-based acceptance. Add a new argument to specify if all useless mark have to be removed, like for scc_filter. * src/twaalgos/simulation.cc: Use the new parameter. * src/twaalgos/postproc.cc: Likewise. Also call do_scc_filter even after WDBA simplification to cleanup trivial SCCs. Preserve state-based acceptance for weak automata. * src/tests/readsave.test: Add one test. * src/tests/dstar.test, src/tests/prodor.test, src/tests/remfin.test, src/tests/sim3.test, wrap/python/tests/automata.ipynb, wrap/python/tests/piperead.ipynb: Adjust expected output. * NEWS: Mention the change.
