gpgtar: Make --files-from and --null work as described.
* tools/gpgtar-create.c (gpgtar_create): Add args files_from and null_names. Improve reading from a file. * tools/gpgtar.c: Make global vars static. (main): Remove tests for --files-from and --null option combinations. Pass option variables to gpgtar_create. -- GnuPG-bug-id: 5027 Signed-off-by: Werner Koch <wk@gnupg.org>
