[Bug-tar] Bug with TAR_OPTIONS and exclude-from in tar 1.29

[Jan Larres]

Hi,

tar 1.29 seems to have broken the use of the --exclude-from option when used
in the TAR_OPTIONS environment variable.

Here's a simple example.

This works:

$ touch foo
$ TAR_OPTIONS= tar cf foo.tar foo
$

But this doesn't:

$ touch foo excludes
$ TAR_OPTIONS="--exclude-from=excludes" tar cf foo.tar foo
tar: : No such file or directory
tar: Error is not recoverable: exiting now
$

This worked before, so something must have changed in tar 1.29.

Thanks,
Jan
