Title:
  apt-ftparchive mangles leading whitespace in package descriptions

Status in “apt” package in Ubuntu:
  Triaged

Bug description:
  The skype package in the Ubuntu partner archive has the following
  description:

  $ dpkg -I ~/partner/pool/partner/s/skype/skype_4.0.0.8-0oneiric1_i386.deb  | sed -n -e'/^ Description:/,$p'
   Description: client for Skype VOIP and instant messaging service
    Skype is software that enables the world's conversations.  Millions of
    individuals and businesses use Skype to make free video and voice calls,
    send instant messages and share files with other Skype users.  Every day,
    people also use Skype to make low-cost calls to landlines and mobiles.
    .
     * Make free Skype-to-Skype calls to anyone else, anywhere in the world.
     * Call to landlines and mobiles at great rates.
     * Group chat with up to 200 people or conference call with up to 25 others.
     * Free to download.
  $

  However, when copied to the Packages file by apt-ftparchive, the
  leading spaces before the bullet points are being lost:

  $ grep-dctrl -sDescription -X -FPackage skype -a -F Version 4.0.0.8-0oneiric1 /var/lib/apt/lists/archive.canonical.com_dists_quantal_partner_binary-i386_Packages

  This is reproducible with the apt-ftparchive in quantal.

  This is a bug; Debian policy 5.6.13 defines two leading spaces on a
  line in a description field as the indicator for a line that must be
  displayed verbatim.  Therefore, apt-ftparchive *must* preserve these
  leading spaces when copying to the Packages file; otherwise clients
  will not format the text the way it was intended.
