[Bug 1653915] [NEW] dpkg -l "foo*" should print only installed packages

[Andrea Bravetti]

Public bug reported:

sibilla ~ # lsb_release -rd
Description:    Ubuntu 16.04.1 LTS
Release:    16.04

sibilla ~ # apt-cache policy dpkg
dpkg:
  Installato: 1.18.4ubuntu1.1
  Candidato:  1.18.4ubuntu1.1
  Tabella versione:
 *** 1.18.4ubuntu1.1 500

        100 /var/lib/dpkg/status
     1.18.4ubuntu1 500
        500 http://it.archive.ubuntu.com/ubuntu xenial/main amd64 Packages

>From the manual:

To list installed packages related to the editor vi(1) (note that dpkg-query does not load the available file anymore  by default, and the dpkg-query --load-avail option should be used instead for that):
            dpkg -l '*vi*'

While "dpkg -l" without package name show only installed packages "dpkg
-l foo*" show a list of installed and not installed (available)
packages.

This bug may be related to #83734 but it's not the same problem.

sibilla ~ # dpkg -l "dpkg*"
ii  dpkg                                                  1.18.4ubuntu1.1                 amd64                           Debian package management system

It should be like this since dpkg-cross is available and not installed:

sibilla ~ # dpkg -l "dpkg*"
ii  dpkg                                                  1.18.4ubuntu1.1                 amd64                           Debian package management system
