=head1 METHODS

=item @items = $entry->get_change_items()
Return a list of change items. Each item contains at least one line.
A change line starting with an asterisk denotes the start of a new item.
Any change line like "[ Raphaël Hertzog ]" is treated like an item of its
own even if it starts a set of items attributed to this person (the
following line necessarily starts a new item).
