Having some thoughts about how to do this is more clean way, perhaps
we should do this as part of bt_shell_run and then introduce .run
callback to bt_shell_menu so it is called as part of bt_shell_run,
under the .run callback the menu can place e.g. DBUS connection setup,
etc, but before it reaches that we can check if it just a help
pending.

We need to:
1) set the top menu
2) populate the submenus without any D-Bus IO
3) turn off the prompt
4) print the help and exit if that's what was requested
5) setup IO for submenus
6) run the mainloop

I guess I could do 2) with a callback from bt_shell_set_menu()
and then do 4) and 5) from a bt_shell_run() callback.

Is that what you expected?
Do you have preferred names for the callback functions?

I think that we can still use the function split from 3/7, did you have
a better name for the functions?

Cheers

Yep.

Id call it .run since it should be the result of bt_shell_run

Not sure I follow, there will be a split between adding submenus and
.run to achieve the 2 stages, or are you talking about some other
split?

We still need to split the functions called in .run between the bits
that populate the submenu, and the bits that will make D-Bus I/O, so
patch number 3 still needs to be exist.

Is assistant_add_submenu() and assistant_enable_submenu() OK, or did
you want a different name?
