* apt-pkg/cdrom.cc:

  - copy only configured translation files from a CD-ROM and not all
    available translation files preventing new installs with d-i from
    being initialized with all translations (Closes: #678227)
  - handle Components in the reduction for the source.list as multi-arch CDs
    otherwise create duplicated source entries (e.g. "wheezy main main")
