[Bug-tar] The --verify option should fail asap when not used properly

[Pavel Raiskup]

Hi, is there possible to fail as early as possible during e.g. trying of
--list & --verify the archive?  Something like the patch attached?

If not, tar may fail hitting the abort() call:

  $ tar -czf /tmp/test.tgz FILE
  $ tar -tWvf /tmp/test.tgz
  tar: This does not look like a tar archive
  tar: Skipping to next header
  Aborted (core dumped)

Original report is here:
