New description:
Currently, the function `_package_lists_from_sage_output` only gives the
latest available version of a package, not the version which is installed.
I propose to actually return a list of triples
{{{
(package_name, installed_version, latest_version)
}}}
where `installed_version` is `None` if the package is not installed and
`latest_version` is the newest available version.
If, for example, arb-2.5.0 is installed but arb-2.6.0 is availble, then
one such triple would be
{{{
('arb', '2.5.0', '2.6.0')
}}}
If arb is not installed, this would be:
{{{
('arb', None, '2.6.0')
}}}
