Same as for filenames starting with "-":

  tar -cvf -  @archive ./@file ./--extract

The alternative would have been to introduce another
option that worked like the -C option; that would
give you syntax along the lines of:

  tar -cvf - file1 --entries-from=archive1 file2 --entries-from=archive

The most interesting implication of this design
is that it leads naturally to a --include option
that specifies file patterns to be retained:

  # Include only one subdir from archive2.tgz:
  tar -czf archive.tgz --include=subdir/ @archive2.tgz
