I prefer this variant as well: "u" is a too common binding for unmarking
in Emacs (it is used in dired, buffer-menu, ibuffer, package-menu, ...).
So unmarking should probably stay on "u" (and unmark all with prefix).

Taylan suggested "C-u U" for this one.  And I think it would be perfect,
but...

Let's say a user has both "foo-1.0:out" and "foo-1.0:doc" installed and
one day they become obsolete.  He decides to upgrade only "out" for some
reason.  May there exist such a situation?

If so, then I think "C-u U" should be used to specify a particular
output for upgrading.  Actually I implemented such specifying of outputs
for installing and deletion ("i"/"d") but not for upgrading (I don't
remember why).
