Why do we need an alternative to cancelling -Su? ;-)
As Xavier noted, -Su needs some user interaction, so -Qu cannot figure out what
user would answer to pacman's questions (however, it can assume some default
answers). Personally, I like the "outdated packages" meaning, so I would prefer
that -Qu would act as a localdb/targetlist filter, like -Qt, -Qd, -Qe (so we
don't need installed size information etc., but user can also use other
command-line switches).
