problem_statement: Add ability to exclude some commands from help menu
It would be nice to be able to explicitly exclude certain commands from being included in the help menu.

For example, the **eof** "command" shouldn't ever show up in the help menu.  This isn't something an end user would ever really want to manually enter as a command, but is something that will be encountered while running a script or when <Ctrl>-d is pressed.

It would be nice to include a member variable which is a list of commands to exclude from the help menu.  By default, "do_eof" should be in there and it is debatable whether or not "do__relative_load" should be there as well.
