	* init.c (gsl_multiset_alloc): remove incorrect (k, n) constraint per
	question from Michael Underwood <munderwood@qis.ucalgary.ca>.  k strictly
	greater than n is permissible.  Incorrect constraint due to copy'n'pase
	from combinations logic.

	* multiset.c (gsl_multiset_valid): likewise

	* test.c: add tests to verify k > n working as expected.
