Bug#248596: Disorderly output of dpkg -S

[Victor Porton <porton@ex-code.com>]

Package: dpkg
Version: 1.10.10
Severity: minor

dpkg -S produces otput with different packages mixed (in the example is out
firstly an entry for gettext then for po-debconf and then again for
gettext).

$ dpkg -S gettextize
gettext: /usr/share/man/man1/gettextize.1.gz
po-debconf: /usr/share/man/man1/debconf-gettextize.1.gz
gettext: /usr/bin/gettextize
libglib2.0-dev: /usr/bin/glib-gettextize
po-debconf: /usr/share/man/fr/man1/debconf-gettextize.1.gz
po-debconf: /usr/bin/debconf-gettextize

It should be out in order (prefereably sorted by apckage name) at least on
a cmd line option.
