[Bug-tar] Recursing bug

[Lutz Donnerhacke]

Hi,

I'v added a new test to check if the positional arguments --recursion and
-no-recursion works as expected.
Quoting from the documentation:
************************************************************************
   The `--no-recursion' and `--recursion' options apply to later
   options and operands, and can be overridden by later occurrences of
   `--no-recursion' and `--recursion'.  For example:

     $ tar -cf jams.tar --no-recursion grape --recursion grape/concord

   creates an archive with one entry for `grape', and the recursive
   contents of `grape/concord', but no entries under `grape' other than
   `grape/concord'.
************************************************************************

It does not work in 1.27.1, simply because the global argument parsing flag
is used instead of the stored flags. One example is:
 ~/tar-1.27.1$ fgrep -n1 recursion src/create.c
 1169-
 1170:  if (!recursion_option)
 1171-    return;

There are other refences, and I'm not sure how to fix it correctly. So I
provide a new test for this behavior.

Thank you for your work.
