Rozycki <macro@embecosm.com> Date: Wed Jan 18 23:38:50 2023 +0000 GDB: Add references to erased args in cli-decode.c Complement commit 1d7fe7f01b93 ("gdb: Introduce setting construct within cmd_list_element") and commit 702991711a91 ("gdb: Have setter and getter callbacks for settings") and update inline documentation accordingly for `add_set_or_show_cmd' and `add_setshow_cmd_full_erased', documenting the `args' parameter and removing references to `var', `set_setting_func' and `get_setting_func'.
