A nice code reduction!

I wonder, however, if we could somhow turn things around by introducing
something like

	split_and_do_for_each(item_p, length, string, delimiter)
		... <do something with item_p and length> ...

that both string_list_split() *and* add_strategies() could use? We would
then be able to avoid allocating the list and duplicating the items in the
latter case.
