Hm. Portage disagrees:
$ python3
>>> import portage
>>> import portage._sets
>>> conf = portage._sets.load_default_config(portage.settings,
>>> portage.db[portage.root])
>>> world = conf.getSetAtoms('world')

So I no longer consider this a bug (or that the package I'm interested
in is in @world at all), but I definitely think the wiki should be
clearer that @world does not include dependencies. That does mean "-O"
is correct in the emerge version.
Unfortunately, that leaves me with checking for installed packages
using @installed, which feels gross since it might not agree with
@world + deps in some situations. It works, though.
