TST_EXP_VAL(GETGROUPS(gitsetsize, groups_get), 1) ?

Also I suppose that we should make sure that the groups_get[0] value is
not equal to the groups_set[0], expecially with -i 2

So maybe:
	groups_get[0] = ~groups_set[0];

TST_EXP_EQ_LI(groups_get[0], groups_set[0]);

At least that will produce TFAIL results if they don't match, which is
missing here.

Do we really need this? I suppose that any random value will do, e.g.

	groups_set[0] = 42;

is going to be as good as anything else.
