Bug#763708: apt man page should show all action arguments too

[積丹尼 Dan Jacobson <jidanni@jidanni.org>]

Package: apt
Version: 1.1~exp3
Severity: wishlist
File: /usr/share/man/man8/apt.8.gz

Please make

       list
           list is used to display a list of packages. It supports shell
           pattern for matching package names and the following options:
           --installed, --upgradable, --all-versions are supported.

Say

       list [pattern]
           list is used to display a list of packages. It supports shell
           pattern for matching package names and the following options:
           --installed, --upgradable, --all-versions are supported.

and same with the rest, like the dpkg man page already does.
Also make sure apt --help shows all the arguments too.

Yes I know they are already there in the SYNOPSIS.
