What about regress?
I'm not a native English speaker, so maybe someone can suggest something better.

I'm trying to convert it to a doubly linked list, but I'm not sure if I
understand well how they work.

I don't see how _notmuch_message_list_append works. It says "node can of course
point to an arbitrarily long list of nodes", but the code is:

void
_notmuch_message_list_append (notmuch_message_list_t *list,                
                  notmuch_message_node_t *node)                            
{   
    *(list->tail) = node;
    list->tail = &node->next;
}

Should not be something like:

void
_notmuch_message_list_append (notmuch_message_list_t *list,                
                  notmuch_message_node_t *node)                            
{   
    notmuch_message_node_t *next_node;

    *(list->tail) = node;
	for (next_node = node->next; next_node->next != NULL;
	     next_node = next_node->next);
	list->tail = &next_node->next;
}

Do I miss something? Or the function is just designed to work on a single node
not a list of them?
