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