ui: stdio: replace newlines with whitespaces in prompt messages

The line-based protocol currently used cannot handle this properly, so
introduce this as a stop-gap measure - otherwise messages might be cut
off.

This makes it work for now, and the text is wrapped correctely for the
screen width in the TUI anyway - which is the only user of this so far.

Will be reworked properly later on.
