If you don't understand me, please try to simulate/think of _without
any help_: what happens, if you want to remove the
first node of a list with alpm_list_remove_node()... If you managed to
do it, you will understand that sentence;-)
(Hint: node->prev points to the tail in that case)

Some more issues:
1. You simply forgot about resetting the tail pointer when you remove
the last element with alpm_list_remove.
2. As I see, alpm_list_remove_node is used nowhere in the code, and
dangerous (when you remove the first or last node, "interesting" things
can happen); so that should be removed.
