* src/ltlvisit/reduce.hh, src/ltlvisit/reduce.hh: Add Reduce_Containment_Checks and Reduce_Containment_Checks_Stronger flags, and call reduce_tau03. * src/ltlvisit/contain.hh (reduce_tau03): Make "stronger" the default. * src/ltlvisit/contain.cc: Style. * src/ltltest/reduc.cc: Simplify using the reduce() interface instead of reduce_tau03. * src/tgbatest/ltl2tgba.cc: Likewise. Add -fr5, -fr6, and -fr7 options. * src/tgbatest/spotlbtt.test: Remove cases using "-c", since its current implementation is not always correct (and apparently reduces less than -fr7).
