False/True are problematic in Python, and I don't like that the enum is op::False but the constructor formula::ff(). So let's just use ff and tt everywhere, and also eword instead of EmptyWord. * src/ltlast/formula.hh (False, True, EmptyWord, AP, is_false, is_true): Rename to... (ff, tt, eword, ap, is_ff, is_tt): ... these. * iface/ltsmin/ltsmin.cc, src/ltlast/formula.cc, src/ltlvisit/apcollect.cc, src/ltlvisit/dot.cc, src/ltlvisit/mark.cc, src/ltlvisit/mutation.cc, src/ltlvisit/print.cc, src/ltlvisit/relabel.cc, src/ltlvisit/simpfg.cc, src/ltlvisit/simplify.cc, src/ltlvisit/snf.cc, src/ltlvisit/unabbrev.cc, src/twa/acc.cc, src/twa/acc.hh, src/twa/formula2bdd.cc, src/twaalgos/gtec/gtec.cc, src/twaalgos/hoa.cc, src/twaalgos/ltl2taa.cc, src/twaalgos/ltl2tgba_fm.cc, src/twaalgos/neverclaim.cc, src/twaalgos/product.cc, src/twaalgos/remfin.cc, src/twaalgos/safety.cc, src/tests/parseerr.test, src/tests/utf8.test, wrap/python/spot.py: Adjust.
