apt-cache fails to filter PreDepends

Bug Description

apt-cache fails to filter out "PreDepends" when using:

apt-cache --no-pre-depends $package


apt-cache -o APT::Cache::ShowPre-Depends=0 $package

works fine like the other options for "Depends", "Recommends", "Suggests", "Conflicts", "Breaks", "Replaces", and "Enhances", so this looks like a bug in apt to me.

It's supposed to work according to the man page, so it sure looks like a bug. :-)

apt-cache -o APT::Cache::ShowPre-Depends=0 $package
works though, and that's the correct name for the config option (as it is written with this dash everywhere else too).

But don't worry, even i got that wrong while implementing it… --pre-depends acts on the config option without dash - obviously it doesn't work this way…

Oh, right! I probably got it wrong because I was following apt-cache's output, which uses "PreDepends". :-)

    - run update-apt-xapian-index in apt.cron
    - support apt-key net-update and verify keys against master-keyring
    - run apt-key net-update in cron.daily
    - different example sources.list
    - APT::pkgPackageManager::MaxLoopCount set to 5000
    - apport pkgfailure handling
    - ubuntu changelog download handling
    - patch for apt cross-building, see http://bugs.debian.org/666772

  [ Steve Langasek ]
  * Drop upgrade handling for obsolete conffile /etc/apt/apt.conf.d/01ubuntu,
    removed in previous LTS.
  * prepare-release: declare the packages needed as source build deps.

apt (0.9.6) unstable; urgency=low

  [ David Kalnischkies ]
  * apt-pkg/cdrom.cc:
    - fix regression from 0.9.3 which dumped the main configuration
      _config instead of the cdrom settings (Cnf) as identified and
      tested by Milan Kupcevic, thanks! (Closes: #674100)
  * cmdline/apt-get.cc:
    - do not show 'list of broken packages' header if no package
      is broken as it happens e.g. for external resolver errors
    - print URIs for all changelogs in case of --print-uris,
      thanks to Daniel Hartwig for the patch! (Closes: #674897)
    - show 'bzr branch' as 'bzr get' is deprecated (LP: #1011032)
    - check build-dep candidate if install is forbidden
  * debian/apt-utils.links:
    - the internal resolver 'apt' is now directly installed in
      /usr/lib/apt/solvers, so don't instruct dh to create a broken link
  * doc/apt-verbatim.ent:
    - APT doesn't belong to the product 'Linux', so use 'APT' instead
      as after all APT is a big suite of applications
  * doc/examples/sources.list:
    - use the codename instead of 'stable' in the examples sources.list
      as we do in the manpage and as the debian-installer does
  * doc/apt-get.8.xml:
    - use apt-utils as package example instead of libc6
  * apt-pkg/contrib/cmdline.cc:
    - apply patch from Daniel Hartwig to fix a segfault in case
      the LongOpt is empty (Closes: #676331)
    - fix segfault with empty LongOpt in --no-* branch
  * ftparchive/apt-ftparchive.cc:
    - default to putting the Contents-* files below $(SECTION) as apt-file
      expects them there - thanks Martin-Éric Racine! (Closes: #675827)
  * apt-pkg/deb/deblistparser.cc:
    - set pkgCacheGen::Essential to "all" again (Closes: #675449)
  * apt-pkg/algorithms.cc:
    - force install only for one essential package out of a group
  * apt-pkg/aptconfiguration.cc:
    - if APT::Languages=none save "none" in allCodes so that the detected
      configuration is cached as intended (Closes: #674690, LP: #1004947)
  * apt-pkg/cacheiterators.h:
    - add an IsMultiArchImplicit() method for Dep- and PrvIterator

  [ Justin B Rye ]
  * doc/apt-cdrom.8.xml:
    - replace CDROM with the proper CD-ROM in text
    - correct disc vs. disk issues
  * doc/apt-extracttemplates.1.xml:
    - debconf is not DebConf
  * doc/apt-get.8.xml:
    - move dselect-upgrade below dist-upgrade
    - rev...
