Thanks, so this updated patch uses installed with --installed and avail
otherwise. After checking the man page, I also added completion of
reinstall and auto-removal for - and + suffixes.

Just for note Felix, while technically possible, I'd really recommend
against trying to ever use bash completions with zsh.

A _deb_packages_update_upgradable function could check
(( $+commands[aptitude] )) and offer all packages as a fallback.
Or one of the options Axel mentions - if someone wants to do that.

It's often not as trivial as it might first seem without a copy of the
command to test combinations against. I probably need to install yet
another VM to cover Debian given a large number of Debian specific
completions. Out of interest, what is the recommended apt* tool these
days? Is aptitude the best or most powerful with apt as the simplified
interface and apt-get just a historic relic?
