[Bug-tar] --verify vs absolute paths

[Bdale Garbee]

Debian bug 230064 against my packaging of tar 1.13.92 points out that --verify
raises a 'cannot stat' error when handed the absolute path to a file hierarchy
to verify against.  For example, the following command fails when run from any
directory other than '/' as shown:

  $ mkdir /tmp/foo; tar cpf /tmp/foo.tar /tmp/foo --verify
  tar: Removing leading `/' from member names
  tar: tmp/foo: Warning: Cannot stat: No such file or directory
