[gnulib-tool-py] Modes --import and --add-import

[Dmitriy Selyutin]

I've found an interesting piece of code:

# This code helps migrating from --import to --add-import or --update. It can

  # be removed on 2012-01-01.

  if test "$mode" = import && test $# = 0; then

    echo "gnulib-tool: cowardly refusing to erase the module list." 1>&2

    echo "The meaning of the option '--import' has changed." 1>&2

    echo "See the documentation at" 1>&2

    echo "<http://www.gnu.org/software/gnulib/manual/html_node/Modified-imports.html>." 1>&2

    echo "For updating to a newer version of gnulib, use" 1>&2

    echo "  gnulib-tool --add-import" 1>&2

    echo "For restoring files that were omitted from version control, use" 1>&2

    echo "  gnulib-tool --update" 1>&2

    func_exit 1

  fi

Does that mean that we can now delete this option and use --add-import only?
