Yes, that is in fact the point here. This is the same as for the
corresponding apt-get command. If the user does not want to see new
packages, they will be removed again from the list in the next step. It
also shows packages which will be removed during an upgrade, which might
also be of interest, although currently my code does not collect this
information.

Yes, if only upgrades for already installed packages should be displayed
this is certainly better. It looks like this doesn't even need the sort,
and probably the --allow-untrusted isn't necessary either (I don't have
any untrusted mirrors in my sources.list to verify this, though). At
least updates for "holds" are shown this way.
