It is a common requirement to automatically execute some command after "init". This can be achieved, either in scripts or through OpenOCD command line, by explicitly calling "init" followed by the commands. But this approach fails if the request for post-init commands is spread across configuration files; only one of the files can split pre-init and post-init status by calling "init". The common workaround is to "rename" the command "init" and replace it with a TCL proc that calls the original "init" and the post-init commands. E.g. in Zephyr script [1]. To simplify and formalize the post-init execution, use a TCL list that contains the list of commands to be executed. Every script can contribute adding new commands, e.g. using "lappend". In the same way, formalize the pre-shutdown execution with a TCL list of user commands to be executed before OpenOCD exit. Document them and add trivial examples. Drop from documentation the suggestion to rename "shutdown".
