Bug introduced in abe2c08b, visible in tests/python/product.ipynb,
and tests/python/acc_cond.ipynb.

for isweakscc.hh.
Operator &= used to always move Fin to the front, it does not anymore.
The only thing it does now is to merge Inf(x)&Inf(y) as Inf({x,y}).
Operator |= is now symmetrical and merges Fin()s.
Fixes#253.
* spot/twa/acc.cc, spot/twa/acc.hh: Simplify &= and make |= symmetrical.

These two functions were doing almost identical work, the only
difference was the way to select the SCC to keep. Now we have a more
uniform way to do that. Closes#172.
* bin/autfilt.cc: Offer a unique --decompose-scc option, but keep
--decompose-strength as an alias for backward compatibility.
* spot/twaalgos/strength.cc, spot/twaalgos/strength.hh: Rename
decompose_strength as decompose_scc, and handle a way to list
all SCC numers in the string specifier. This gets rid
of the nearly identical
* tests/core/scc.test, tests/core/strength.test,
tests/python/decompose.ipynb, tests/python/decompose_scc.py: Adjust
test cases.
* NEWS: Adjust.
Fixes#271, reported by Henrich Lauko.

of disjunction of Fin.

value is a Boolean formula.

* python/spot/impl.i: Add bindings for are_isomorphic for the above
test.
* NEWS: Mention the news.
Fixes#269.
* spot/twaalgos/stats.cc: Use twa_statistics instead of
twa_sub_statistics when %t is not used.
* bin/common_aoutput.cc: Likewise, also fix %S to use twa_statistics
instead of num_states(), and document that %s,%t,%e all return
statistics about the reachable part of the automaton.
* tests/core/format.test: Add more tests.
* NEWS: Document the issue.
* NEWS: Mention the modification.
