Subject: [PATCH] mv: ensure line prints (#1890)

Previously this used `print` instead of `println`, and as a result the
prompt would never appear and the command would hang. The Rust docs
note this about print:

> Note that stdout is frequently line-buffered by default so it may be
> necessary to use io::stdout().flush() to ensure the output is emitted
> immediately.

Changing to `println` fixes the issue.

Fixes #1889.
