Make “apt-get update” show “x packages can be upgraded”
I'm learning the CLI interface of Advanced Packaging Tool. From the output of apt(8) when its stdout isn't a terminal, it isn't suitable for "scripts expecting stable programming interface", so I'm taking a look at apt-get(8).
One difference between apt update and apt-get update is that the latter is missing a final line after all cache has been updated:
8 packages can be upgraded. Run 'apt list --upgradable' to see them.
I want to know how I can get this exact line displayed with apt-get(8).

From man 8 apt:
... enables some options ...
Then I went through /usr/share/doc/apt/examples/configure-index.gz (using zcat(1) to show text content) and noticed this option:
apt::cmd::show-update-stats
So I worked out the following command that did exactly what I wanted:
# apt-get -o apt::cmd::show-update-stats=true update
Tested to be working on Xenial and Bionic.

man apt-get shows:
-s, --simulate, --just-print, --dry-run, --recon, --no-act
No action; perform a simulation of events that would occur based on
the current system state but do not actually change the system.
Locking will be disabled (Debug::NoLocking) so the system state
could change while apt-get is running. Simulations can also be
executed by non-root users which might not have read access to all
apt configuration distorting the simulation. A notice expressing
this warning is also shown by default for non-root users
(APT::Get::Show-User-Simulation-Note). Configuration Item:
APT::Get::Simulate.
So if you just do:
apt-get upgrade --dry-run
it will output:
...
4 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
