spot/tests/python/parity.py
Alexandre Duret-Lutz 566a43dd17 improve readability of parity(false, true, 5)
* spot/twa/acc.hh: Introduce parity_min_odd(n) and friends.
* spot/twaalgos/determinize.cc, spot/twaalgos/rabin2parity.cc,
spot/twaalgos/toparity.cc: Use them.
* tests/python/parity.py: Call each function exhaustively.
* NEWS: Mention the new functions.
