[demo/PATCH 1/3] string-list: introduce string_list_init()

[Jonathan Nieder <jrnieder@gmail.com>]

Instead of asking callers to

	memset(&list, 0, sizeof(list));
	list.strdup_strings = strdup_strings;

we can take care of that ourselves, providing the flexibility
to change the details of string_list layout later if wanted.
