+       Allow output files to overwrite input files (bug #21280).
+
+       * data-list.c (cmd_data_list): Manage file handle reference
+       counts.
+
+       * data-reader.c (struct dfm_reader): Add `lock' member.
+       (dfm_close_reader): Simplify, as reference counting is now
+       separate from locking.
+       (dfm_open_reader): Lock file.
+
+       * data-writer.c (struct dfm_writer): Add fh_lock, replace_file
+       members.
+       (dfm_open_writer): Lock file and prepare for replacement.
+       (dfm_close_writer): Unlock file and replace it.
+
+       * file-handle.q (cmd_close_file_handle): Use fh_unname.
+       (fh_parse): Don't distinguish existing handles for a given file
+       name from new ones.  Manage file handle reference counts.
+
+       * get.c (parse_read_command): Manage file handle reference counts.
+       (parse_write_command): Ditto.
+       (mtf_close_all_files): Ditto.
+
+       * inpt-pgm.c (cmd_reread): Manage file handle reference counts.
+
+       * print-space.c (cmd_print_space): Manage file handle reference
+       counts.
