	* src/str.c (gnm_string_dump): New function for debugging.

	* src/dependent.c: Use new "compact set" implementation for the
	micro hash.  Use alternative (and very efficient) storage methods
	for 1-element sets and for {2,3}-element sets.
	(micro_hash_insert): When resizing, make sure the hash table end
	up somewhat dense.  (Since we are using a pool allocator for
	cells, the entries are extremely well distributed in the hash
	table.)
