Description of problem:
Tar does not honor --directory option for --remove-files, it tries to remove files in the current working directory instead.


Version-Release number of selected component (if applicable):
tar-1.26-29.el7.x86_64


How reproducible:
always


Steps to Reproduce:
1. cd $HOME
2. rm -f tartest.tar
3. mkdir -p indirectdir/test
4. touch indirectdir/test/afile
5. tar --remove-files --append --atime-preserve --directory $HOME/indirectdir --mode 444 --file $HOME/tartest.tar test/afile
6. ls indirectdir/test/afile


Actual results:
ls indirectdir/test/afile
shows the file still exists


Expected results:
ls: indirectdir/test/afile: No such file or directory


Additional info:
tar-1.15.1-32.el5_8 in RHEL 5 and tar-1.23-14.el6.x86_64 in RHEL 6 work as expected
