Related to issue #351. * spot/twaalgos/sccfilter.cc: When handling weak automata, we know they are very-weak if the SCC count is equal to the number of states. * tests/core/dca2.test, tests/core/monitor.test, tests/core/parity2.test, tests/core/randomize.test, tests/core/readsave.test, tests/core/remfin.test, tests/core/sccsimpl.test, tests/core/wdba2.test, tests/python/dualize.py, tests/python/remfin.py: Adjust output.
