Improve the "next" shortcut.
* src/gdbmtool.c (open_handler): Close the previously
opened database.
(close_handler): Free the file name.
(print_dir_handler): Print the number of buckets.
(command_repeat_type): New enum.
(command) <repeat>: Change type to enum command_repeat_type.
(command_tab): Update accordingly. Mark "next" with REPEAT_NOARG.
(run_last_command): Handle REPEAT_NOARG separately.
* NEWS: Document the shortcut.
* doc/gdbm.texi: Likewise.
* src/debug.c (datbuf_format): Don't represent
bytes after the end of datum as zeros.
(gdbm_debug_datum): Print datum size.
