51 * The address book is read into memory. We set up an address list
52 * containing all address book entries. Next we make the completion
53 * list, which contains all the completable strings, and store a
54 * reference to the address entry it belongs to.
55 * After calling the g_completion_complete(), we get a reference
56 * to a valid email address.
58 * Completion is very simplified. We never complete on another prefix,
59 * i.e. we neglect the next smallest possible prefix for the current
60 * completion cache. This is simply done so we might break up the
61 * addresses a little more (e.g. break up alfons@proteus.demon.nl into
62 * something like alfons, proteus, demon, nl; and then completing on
63 * any of those words).
