Subject: [PATCH] Fix for non-interactive mode when there is no terminal

Originally the code called Refresh(nil). This had handling for
non-interactive mode where the code would return without printing
a prompt. When issue169 was initially fixed, the interactive
part of this was mistakenly dropped. This puts the interactive
check back into the flow.
