I always thought g_list_alloc() allocated a GList (almost makes sense,
doesn't it? :)  Because of that I'd always get a first item of NULL (since
I would always alloc a list, then append items).  But you're right, if you
just append to a NULL list, glib automatically creates the list for you.
The reason I got confused was because using a NULL first item is usually
the way I implement a linked list.  It makes logic easier by just having
to add to list->next, and not worrying about whether 'list' is the head
pointer.

Sorry for the mistake.
