Title:
  apt-cache --installed fails to correctly deal with virtual packages

Status in “apt” package in Ubuntu:
  New

Bug description:
  When using the --installed switch of apt-cache, the result seems to be
  bad when it has to deal with virtual packages. E.g.:

  $ apt-cache depends xfonts-base
  xfonts-base
    Depends: xfonts-utils
   |Suggests: xfs
    Suggests: <xserver>
      tightvncserver
      vnc4server
      xnest
      xserver-xephyr
      xserver-xfbdev
      xserver-xorg
      xvfb
    Replaces: <xfonts-misc>
    Replaces: <xfonts-misc:i386>

  Now with the --installed switch:

  $ apt-cache --installed depends xfonts-base
  xfonts-base
    Depends: xfonts-utils
      tightvncserver
      vnc4server
      xnest
      xserver-xephyr
      xserver-xfbdev
      xserver-xorg
      xvfb

  It correctly removes "Suggests: <xserver>", but fails to remove all
  the content of the virtual package.
