Feedback on Example feature

1. For each "line" of the help, I would suggest adding the space between the end of the current line and the input. Currently you have to manually press space.

2. That the fuscia "help pane" disappears while the command is running is a bit disconcerting. It would be nice if the verbose output (basically saying that the long running operation is running) was placed in the "help pane".

3. Making the cursor into some kind of spinning activity indicator would be helpful. While we've resisted this in the main CLI, the shell is interactive so this is more jarring.
