Do not allocate more than necessary

Browse Source 
Review b10cba0e0a and 7a16f4582d:
	* lib/groupio.c (merge_group_entries): Do not allocate more than
	necessary (sizeof char* instead of char).
	Thanks for Tomáš Mráz (alioth#313962)
	* lib/groupio.c (merge_group_entries): Document that new_members
	is correctly NULL terminated. (alioth:#313940)
