[Bug 1995790] Re: apt-patterns does not work as described in man pages

[Mekaniserad Apelsin]

Just tested on bullseye and both commands below works as
expected|indented, packages marked as automatically installed (and no
longer needed) and packages with configuration files left are removed,
as per  apt subcommand.

$ sudo apt purge '~g|~c'
$ sudo apt remove '~g|~c'

Title:
  apt-patterns does not work as described in man pages

Status in apt package in Ubuntu:
  New

Bug description:
  The awesome apt has a some wonderful tips on their EXAMPLES section
  (printed below). The choice of name to "garbage" might not have been
  the best but the function is extremely useful.

  $ man apt-patterns | sed '/EXAMPLES/,/^[^ ]/!d;/^[^ ]/d'
         apt remove ?garbage
             Remove all packages that are automatically installed and no longer needed -
             same as apt autoremove

         apt purge ?config-files
             Purge all packages that only have configuration files left

         apt list '~i !~M (~slibs|~sperl|~spython)'
             List all manually-installed packages in sections matching libs, perl, or
             python.

  Lets mark a package as automatically installed, and use the examples.

  $ sudo apt-mark auto shotwell
  shotwell set to automatically installed.

  $ sudo apt remove ?garbage

  Abort.

  Apt-patterns works as it should everywhere else, as far as I can see,
  it works wonders with ie `apt list '~g|~c'` and many other
  applications. I used `apt purge '~g|~c'` successfully in Ubuntu 20.04
  for years, so I feel this is a regression.
