Yeah, I see. Sigh.
If we select 'curr', then the latest version of all installed packages
is selected by the picker and will be shown in the pending view, and
gets fed into the solver.
I guess this is technically wrong: really we should ask the solver to do
SOLVER_UPDATE | SOLVER_SOLVABLE_ALL, which will come up with a solution
which updates all installed packages to the latest possible version,
subject to any other constraints which exist.
I suspect there's no difference between these two at the moment, though.
Not sure how to do this properly, though.
