[Message part 1 (text/plain, inline)]
Running

   emacs -Q File-Corresponding-0.003.tar.gz

on that file from

   http://search.cpan.org/CPAN/authors/id/J/JO/JOHANL/File-Corresponding-0.003.tar.gz

(about 14 kbytes) produces a buffer like

   drwxrwxrwx       0/0             0 File-Corresponding-0.003
   -r--r--r--       0/0          1274 Build.PL
   -r--r--r--       0/0           382 Changes
   -r--r--r--       0/0          1272 Makefile.PL
   ...

where I hoped it would show the directory part of each name, the same as
shown by "tar tvf" (GNU tar 1.20),

   File-Corresponding-0.003
   File-Corresponding-0.003/Build.PL
   File-Corresponding-0.003/Changes
   File-Corresponding-0.003/Makefile.PL
   ...

Such a file is generated by the perl Archive::Tar module.  It uses the
posix style magic "ustar\0", with digits "00" in the `version' field.
But I think tar-header-block-tokenize only recognises a nul "\000" in
that version field (in addition to ``OLDGNU'' style which is a space).

I get some joy from the change below.  Are those two places the only
ones wanting to match the extra form?

	* tar-mode.el (tar-header-block-tokenize): Recognise posix
	"ustar\0\060" magic for long filenames.
