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