[Toaster] [RFC] Handling IMAGE_INSTALL_append

And I still agree with that.

Trying to have the user do this opens the door to trivial but blocking defects, and the GUI experience is supposed to be superior and more guided than the raw command line experience.

The fall back is to have the front end interface enforce this invisibly, in other words always force a leading space when it writes this value to the backend but present/accept a trimmed value. This is something that could be done quickly, but then we are spreading this arcane syntax rule to the frontend away from the presumably more intelligent backend.
