	* src/ltlvisit/reduce.cc (reduce): Repeat the reduction as
	long as the formula changes, it makes more sense when
	combining algorithm.  E.g. basic reductions can help language
	containment and vice-versa.

	* src/ltltest/reduc.cc (main): More cases to test.
	* 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.

65
66
67
	* src/ltlvisit/contain.cc (reduce_tau03_visitor): Simplify 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).

	* src/misc/bddalloc.cc (bdd_allocator::bdd_allocator): Count the
180
181

	(ltl_to_tgba_fm): Add a new option "containment_checks" to enable
	some language containment checks (via emptiness checks) during the
	translation.  This first attempt currently only use containment
	checks to merge states bisimulating each other.

201
202
	* src/tgba/bdddict.cc (bdd_dict::unregister_variable): Correctly
	call release_n(), not remove() to repopulated the freelist of
	anonymous BDD variables.  New code I'm working on triggered an

	* src/tgbaalgos/gtec/gtec.cc, src/tgbaalgos/gtec/gtec.hh:
	(couvreur99_check_shy_ssp): Add a onepass_ attribute to
	disable the "shyness", and do not increment pos before calling
	find_state since gspn's implementation uses it.
	* iface/gspn/ssp.cc: Enable "onepass_" for all "shy" variants,
	and also fix find_state for the case where onepass_ is
	disabled (but I do not yet know why the latter fix isn't enough).

255
	* src/tgbaparse/public.hh (tgba_parse): Take two environments
	instead of one : one for the atomic propositions, and one
	for the acceptance conditions.  This way it's easy for
	the tools in iface/gspn/ to require some atomic proposition
	to be declared and allow any acceptance conditions (there is nothing
	to adjust in this files because of the default value of the argument).
	* src/tgbaparse/tgbaparse.yy: Adjust.
	* src/tgbatest/ltl2tgba.cc, src/tgbatest/readsave.cc,
	src/tgbatest/reductgba.cc, src/tgbatest/tgbaread.cc: Adjust calls.

	* src/tgbaalgos/gtec/gtec.cc (couvreur99_check_shy::check):
	Reorganize this function so that syntactically there is only one
	loop over the successors, and not two.  Call reintroduce the call
	to couvreur99_check_shy::state_index(), needed by SSP, and
	suppress that to index_and_insert introduced on 2004-12-29.  Also
	split the "group" option in two: "group" and "group2".  "group2"
	is the equivalent of the older "group", while the new "group" is
	weaker and faster.

	(tau03_opt_search): Add option "ordering" (off by default).
	If enabled, initialize an explicit ordering for acceptance
	conditions into the new member "cond" (a vector of bdds).
	(project_acc): New helper function for projecting a set of
	acceptance conditions to a subset that maximizes the number
	of initial consecutive conditions covered by the set in the
	condition ordering.
	(dfs_blue): Implement the ordering heuristic.
	(dfs_red): Use a sentinel in condition_stack to avoid explicit
	checks for the stack's emptiness.
	Consider also the conditions in acc when checking for the
	completion of an accepting cycle.
	Fix the implementation of condition heuristic.
	Implement the ordering heuristic.
	Simplify the removal of elements from condition_stack (due to
	the way in which elements are pushed on the stack, there can
	be at most one element with a given depth in the stack at any
	one time).
