Oh, great. This is precisely what I had in mind but to come back to the
problem at hand the way to show upgradable packages would be to first
mark them (package-menu-mark-upgrades) and then filter marked?

I wonder whether it would not be nice to be able to list all upgradable
packages and then give the user an option of marking them one by one.
