Fix Issue heapwolf#25: Inappropriate Redrawn Multi-Line Asks

heapwolf#25

Prompts were causing bad user experience in situations where
the prompt contains multiple lines. This is because prompt-sync
will redraw the prompt as you type, and assumes it only takes
up one line.

The fix provided prints the whole ask string, before reassigning
ask to be only the final line of the prompt. This way, redraws
don't affect above lines.
