* apt-pkg/depcache.cc:

  - party revert fix in 0.8.11.2 which marked all packages as manual
    installed if the FromUser bit is set in the MarkInstall call.
    The default for this bit is true and aptitude depends on the old
    behavior so the package is only marked as manual if its not marked
    ("old" behavior) or if automatic installation is enabled - which
    aptitude disables always (see also #613775)
