	options.
	* src/tgbatest/spotlbtt.test: Remove cases using "-c", since its

	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.
