[Bug-tar] --exclude-from using process substitution fails

[Bdale Garbee]

A user of my Debian package of tar reports a problem in version 1.16 where
doing something like

        tar -cf test.tar ~/.mozilla --exclude-from=<(cat /etc/group)

results in the following error output:

   tar: /dev/fd/63: No such file or directory
   tar: Error is not recoverable: exiting now

The user reports that commenting out the call to closeopen() at line 2257 
of tar.c seems to fix this problem.
