Bug: After specifying I want to use a GitHub Repo, the ask prompt is in-between data

This might be due to a terminal resize, as I've noticed that resizing the terminal during a brew upgrade will cause brew to continue on the old row location, which is now in-between data. Perhaps we need our TTY helpers to note the terminal row and height before setting up an alt tty, and when restoring, check if the height has changed if so move the cursor to the new height after restoring the old TTY.
