* src/ltlvisit/basicreduce.cc (basic_reduce_visitor::visit):
Simplify the formula again after FX->XF and GX->XG permutations.
This is so that formulae like GFXXa become GFa and not just GFXa.
* src/ltlvisit/contain.cc (reduce_tau03_visitor): Fix a typo
in the rules for i|j or i&j, resulting in missing simplifications.
