+Subject: [PATCH] Fix the --add-file option.
+
+* src/common.h (name_more_files): New proto.
+(files_from_option): Remove.
+* src/names.c (name_more_files): New file.
+(names_options): Fix declaration of the
+add-file option.
+(names_parse_opt): Handle --add-file.
+* src/tar.c (struct tar_args): Remove the input_files member.
+Change all uses: use name_more_files() instead.
+* tests/Makefile.am: Add new test.
+* tests/add-file.at: New testcase.
+* tests/testsuite.at: Add new test.
