Now also for a fix of the sphere distribution. Unless someone objects I'll check in the patch below.

	* include/ext/random.tcc
	(uniform_on_sphere_distribution::__generate_impl): Reject
	vectors with norm zero.

I would have done: while (__sum < small || __sum > large)
but testing exactly for 0 and infinity seems good enough.
