feat(shell): support completion in the middle of a prompt (#450)

Browse Source 
I think it's better to insert our output at the cursor so this can be
invoked in the middle of a prompt. Previously we would assume the cursor
is at the end of the prompt and invocation in the middle of one would
discard everything after the cursor.
