* src/tgba/tgbaexplicit.cc (tgba_explicit::get_acceptance_condition):

Browse source 
Do not treat true and false specially.  Otherwise it breaks
translation of F(false).
* src/tgbatest/explprod.test, src/tgbatest/tripprod.test: Do not
use true as acceptance condition.

* src/tgbaalgos/ltl2tgba_fm.cc (ltl_trad_visitor): Use Acc[b] as
acceptance condition for Fb, not Acc[Fb].
