string-list: spell all values out that are given to a string_list initializer

STRING_LIST_INIT_{NODUP,DUP} initializers list values only
for earlier structure members, relying on the usual
convention in C that the omitted members are initailized to
0, i.e. the former is expanded to the latter:

	struct string_list l = STRING_LIST_INIT_DUP;
	struct string_list l = { NULL, 0, 0, 1 };

and the last member that is not mentioned (i.e. 'cmp') is
initialized to NULL.

While there is nothing wrong in this construct, spelling out
all the values where the macros are defined will serve also
as a documentation, so let's do so.
